# The Red Ranger Becomes an Adventurer in Another World

The Red Ranger Becomes an Adventurer in Another World (Japanese: 戦隊レッド 異世界で冒険者になる, Hepburn: Sentai Reddo Isekai de Bōkensha ni Naru) is a Japanese manga series written and illustrated by Koyoshi Nakayoshi. It has been serialized in Square Enix's shōnen manga magazine Monthly Shōnen Gangan since October 2020. An anime television series produced by Satelight premiered in January 2025.

## Premise

Leading a sentai team on Earth, Tōgo Asagaki has the ability to change into the superhero Kizuna Red. He unintentionally gets warped into a fantastical world while facing off against the supervillain Breakup King. Unable to find a way home, he joins forces with the sorceress Yihdra Arvoln, who wants to prove herself and restore her family honor, Princess Teltina Liz Wagrel Alvarost, who aims to stop demon seeds from possessing people; and Lowji Mist, Princess Teltina's bodyguard who is enamored of her and envious of Tōgo for upstaging him and appearing to grow close to her. Tōgo frequently frustrates or amazes people because he lacks subtlety and common sense, is unable to hold back in battle, and frequently vaporizes monsters, preventing his comrades from selling their body parts. Additionally, his transformation, powers, weapons, and ability to summon a mecha are not magical in nature and make no sense to magic users.

| The Kizuna Five battles the supervillain Breakup King and his forces. Kizuna Red is forced to face Breakup King alone, but after an explosion, he wakes up in a fantasy world. Six months later, Yihdra Arvoln and her butler Poseidon test adventurers with her golem, disappointed by how weak they are. Tōgo Asagaki arrives and mistakes the golem for an enemy and attacks it. When he transforms into Kizuna Red, Yihdra is shocked because she senses no magic and doesn't understand his weapons and ability to make explosions. He defeats the golem, so she hires him to help her gather mana metal from some ruins. As Tōgo carries her to the ruins, he explains the Kizuna Five battles a supervillain team called the Relationship Enders. Ever since he arrived here, he has seen suffering, so he will do his best to help people while finding a way home. In turn, she explains that her father was once the Royal Scepter, the court mage with a dream of using magic to make people happy, but he was defeated and her family kicked out of the capital. The new Royal Scepter hordes magic for herself, so her dream is to take the position. They battle monsters and find the mana metal guarded by a dragon. Tōgo summons the mecha Maximum Kizuna Kaiser, but it is at low power because it runs on the power of bonds and only Tōgo and Yihdra are in it. He hugs her and tells her to believe in their friendship, and it works and allows them to defeat the dragon. Later, Yihdra decides to form an adventuring party with Tōgo to give her a chance to study his powers and hopefully find a way to get him home. ||||||

| Yihdra examines Tōgo, but cannot find anything unusual about his body, and when she tries to get a blood sample, he refuses as he is afraid of needles. The adventurers Zetsu and Lain mock Yihdra and her father. They decide to settle it in a contest to see who can defeat a unique monster in a dungeon first. When they are attacked by minotaurs, Tōgo foolishly summons the Maximum Kizuna Kaiser, which is too large to fit in the tunnel. Yihdra protects Zetsu and Lain and explains that even after her family was kicked out and her father eventually died, he taught her to help people. The monster, a giant inhuman skeleton, attacks. Tōgo remembers how his team faced a similar villain called Rejectiondra and summons a massive gun called the Victory Kizuna Buster, but it misfires because the other three are still bickering. Tōgo is injured and the other two defend Yihdra while she heals him, earning her respect. This allows the gun to work and destroy the monster. They find an injured old man and take him with them. Zetsu and Lain part ways with them as friends. Yihdra tries to take a blood sample again, but Tōgo is still afraid. The old man escapes his bed and turns into the monster, but a man and woman intercept and destroy him, then extract a demonic seed from his head. ||||||

| Tōgo is broke because he keeps blowing up monsters, preventing him from selling their body parts, so he moves in with Yihdra. Poseidon is upset and threatens to geld him if he tries anything with her. The two who destroyed the monster earlier, Princess Teltina and her bodyguard Lowji Mist, arrive. Teltina explains that demonic seeds have been mutating people and amplifying their power. She suspects Shau'ha, the Royal Scepter, is involved, and asks for help. Lowji objects, as he loves Teltina and only her and wants to be her only hero. He also objects to Tōgo addressing Teltina casually and challenges him to a duel for the right to travel with them. Lowji mocks the Kizuna Red form and fights evenly with him. Red summons the Maximum Kizuna Kaiser, but both Yihdra and Teltina are inside because Red already thinks they are friends. Lowji is enraged thinking Teltina was kidnapped and staggers the mecha, but it knocks him into the sky and defeats him. Lowji tries to go back on his word, but Teltina says they will travel with them. The group goes to the city of Akalina, where everyone lives in fear of Lord Loulugart and a woman tries to ask them to leave. Loulugart attacks them with monsters and has a demonic seed in his hand. Tōgo calls him out on his tyranny and tries to attack him, but the monsters keep teleporting behind him and hitting him. Lowji refuses to help him even when Teltina asks. Yihdra and Teltina cry out when Tōgo takes so much damage his transformation cuts out. ||||||
| 4 | "The Red Ranger and the Blades of Bonds" Transliteration: "Sentai Reddo to Kizuna no Tsurugi" (Japanese: 戦隊（せんたい）レッドと絆（きずな）の剣（つるぎ）) | Ryo Yasumura & Eiichi Sato | Natsumi Morichi | Noriaki Saito | February 2, 2025 (2025-2-2) |
| Rebels led by the woman from earlier, Grossa, cover the group's escape. They learn Loulugart can instantly teleport monsters to his opponents' blind spot, so Yihdra suggests Tōgo and Lowji fight back to back, but Lowji refuses to work with him. Yihdra and Teltina bathe and start to bond. When Teltina leaves, she mischievously tricks Tōgo into entering the bath and seeing Yihdra naked. Lowji jealously steals Tōgo's transformation device. The next day, they attack Loulugart again, but Tōgo cannot transform and is knocked into a river. He has a flashback of Kizuna Silver telling him he is obsessed with forming bonds because he is afraid of being alone. Yihdra retrieves and revives him with CPR, embarrassing her because she had to kiss him. Lowji declares he only cares about Teltina and slays the monsters. A flashback shows he was shunned for lacking magic, but was worthy of his holy sword and Teltina took him in. Loulugart attacks Teltina and forces Lowji to shield her. Tōgo and Yihdra rescue them, so Lowji reluctantly returns the transformation device and confesses he tried to get Tōgo killed since he feared being replaced as Teltina's hero. After Teltina says he is irreplaceable, he still refuses to call Tōgo a friend, but they fight back to back perfectly to slay the monsters and knock Loulugart out. Loulugart's demonic seed suddenly consumes him and grows into an island-sized mass of flesh floating in the sky. ||||||
| 5 | "The Red Ranger and the Demon Queen's Children" Transliteration: "Sentai Reddo to Maō no Ketsuzoku" (Japanese: 戦隊（せんたい）レッドと魔王（まおう）の血族（けつぞく）) | Studio Massket | Atsuhiro Tomioka | Noriaki Saito | February 9, 2025 (2025-2-9) |
| Tōgo summons the Maximum Kizuna Kaiser, with all the party members inside, and carries the mass into outer space to destroy it. Recovering Loulugart's body, Teltina reveals she also has a demonic seed and uses it to summon a wolf called Vrykolakas to devour his seed. A demon called Abudabi appears and reveals he and his brethren have been distributing the seeds to harvest mana to try to unseal their mother, the Demon Queen. He then reveals he planted seeds in Grossa and the rebels and they immediately turned into monsters. Tōgo and Lowji take on Abudabi while Yihdra and Teltina take on the monsters. Teltina is incapacitated when she absorbs too much mana. Abudabi displays knowledge of otherworlders. When Lowji shields Tōgo and is injured, an enraged Tōgo knocks Abudabi into a building while emitting darkness. Shau'ha shows up and incapacitates all the monsters while mocking Yihdra, but Abudabi escapes. While they recover and turn the rebels back to normal, Yihdra tells Tōgo ancient records say the hero who sealed the Demon Queen was an otherworlder. Shau'ha teleports the party to the capital. ||||||
| 6 | "The Red Ranger and the Mage's Dream" Transliteration: "Sentai Reddo to Madōshi no Yume" (Japanese: 戦隊（せんたい）レッドと魔導士（まどうし）の夢（ゆめ）) | Eiichi Sato | Natsumi Morichi | Keiichiro Kawaguchi & Eiichi Sato | February 16, 2025 (2025-2-16) |
| Shau'ha treats Teltina and gives a potion to stop her seed from taking her over. She reveals many of the royals have seeds, but now that they know the seeds come from demons, they'll hopefully give them up. Shau'ha aims to regulate and monopolize the use of magic. When Yihdra argues magic should be shared with everyone, Shau'ha mocks her and says when Yihdra's father was in charge, sharing magic led to widespread crime and disaster. When Tōgo says Shau'ha has a point, a heartbroken Yihdra flees into a blizzard. Tōgo catches up to her and clarifies that he agreed to both of their points, believing working with Shau'ha to combine their ideas will allow magic to be shared safely. Yihdra realizes she is in love with Tōgo. Tōgo later thanks Lowji for shielding him and Lowji thanks him for showing him outer space. Yihdra bathes and fiddles with a piece of mana metal. When she thinks of Tōgo, he is abruptly teleported to her. After initial embarrassment, they speculate that mana metal is connected to the power of bonds, then she apparently has sex with him, leaving them flustered. They have an audience with Teltina's father, Emperor Gunti, to discuss the seeds. Prince Dariel, who despises Teltina, suggests instead of destroying the seeds, they collect and have Shau'ha work on a way to weaponize them, arrogantly saying they can defeat the Demon Queen if she awakens. Gunti agrees and orders all seeds recalled, but assigns Teltina's group to deal with people unwilling to give them up. Yihdra tries to share ideas with Shau'ha, only to be mocked. Later, Yihdra, Tōgo, Teltina and Lowji wander a desert and reach a large cactus. ||||||
| 7 | "The Red Ranger and the Sun Forest" Transliteration: "Sentai Reddo to Taiyō no Mori" (Japanese: 戦隊（せんたい）レッドと太陽（たいよう）の森（もり）) | Cai Yinkai | Keiichiro Kawaguchi | Kenji Seto | February 23, 2025 (2025-2-23) |
| The party goes to the Sun Forest, a forest of cacti in the desert, to investigate the elves and clues to the original hero. Yihdra pricks her finger on a cactus and Tōgo applies a bandage, making her think he proposed. Yihdra is abducted by an elf and Tōgo pursues until Yihdra uses the mana metal to teleport him to her so he can defeat the elf. Lowji and Teltina are attacked by elves and one of them, Raniya, uses a similar device and transformation, Egyptian-themed, to Kizuna Red. Tōgo asks them to stand down and they do. The elves take them to their village and explain the original otherworldly hero teamed up with Raniya's ancestor Amen and passed the device to her. They reveal a prophecy that a red-themed hero will save them and the figure in the mural looks like Kizuna Red. Raniya says they are at war with Azir, the lord of Kukja, who has a seed and the power to control sand. The party agrees to help and Raniya says the Great Elder knew the hero, but she is in hibernation and cannot wake for years. Three men with seeds prepare to attack the village. ||||||
| 8 | "The Red Ranger and Bondkiller" Transliteration: "Sentai Reddo to Bansō Kirā" (Japanese: 戦隊（せんたい）レッドとバンソウキラー) | Makoto Sokuza | Toshiki Inoue | Keiichiro Kawaguchi | March 2, 2025 (2025-3-2) |
| As the elves teach Yihdra and Teltina spells, Raniya confides in Tōgo that Azir used to be her friend. He urges her to defeat and then make up with him. Yihdra becomes jealous seeing them together while he confides that he was orphaned and then adopted by Daigo Shindo, moving in with Daigo, his wife, son Kiyohiro, and daughter Sumika. He was bullied at school but Kiyohiro always saved him. As they grew older, Kiyohiro became jealous that the family paid more attention to Tōgo, allowing the Relationship Enders to turn him into the villain Bondkiller to seek revenge. By spreading and feeding on hatred, Bondkiller was a strong opponent, but the Kizuna Five defeated him and turned him back to normal. Tōgo and Kiyohiro reconciled, but Kiyohiro tended to turn back into Bondkiller whenever he was jealous, forcing Tōgo to defeat him 13 times before he stopped. As the party is impressed by the story, cards rain down and start trapping people inside them, including Teltina and Yihdra. ||||||
| 9 | "The Red Ranger and the Mental Mask" Transliteration: "Sentai Reddo to Kokoro no Kamen" (Japanese: 戦隊（せんたい）レッドと心（こころ）の仮面（かめん）) | Yuuji Kanzaki & Yoshihide Kuriyama | Atsuhiro Tomioka | Hiromitsu Kanazawa | March 9, 2025 (2025-3-9) |
| A man with a seed collects the cards and traps Lowji in one. Azir appears and Raniya points out he used to support equality between the races, but he says he will achieve that by conquest. Azir and the card man escape to the Udold Ruins. Raniya summons a motorcycle so she and Tōgo can pursue. After defeating a man who turned into a monster, the card man taunts them by using the cards as hostages and licking Teltina's card, but Yihdra triggers an explosion that knocks the man out, freeing everyone. Teltina angrily has Vrykolakas devour him. The party confronts Azir, but he summons a sand monster, turns the motorcycle to sand, then sucks Yihdra, Teltina, and Lowji underground, boasting he is invincible in the desert. The three fall into a tomb and are attacked by mummies. Raniya and Tōgo try to fight Azir and his sand monster, but Azir seemingly freezes time to get the advantage. Tōgo tries to warn Azir that his seed will eventually turn him into a monster, but he will not listen and sucks Tōgo underground. Raniya remembers how she and Azir became friends as children. She used to hide behind masks because she was shy, but he got her to open up. She told him the Demon Queen made it so elves lost their eternal youth and he revealed his dream to unite all races. He freezes time again and knocks her out. The others break free from underground and are shocked when Azir takes Raniya's transformation device and uses it to gain her costume and powers. ||||||
| 10 | "The Red Ranger and the Mask of Pain" Transliteration: "Sentai Reddo to Kurushimi no Kamen" (Japanese: 戦隊（せんたい）レッドと苦（くる）しみの仮面（かめん）) | Makoto Sokuza | Natsumi Morichi | Ryo Yasumura | March 16, 2025 (2025-3-16) |
| Azir revels in his new powers and declares his dream will finally come true. As Yihdra, Teltina, and Lowji tend to Raniya, Tōgo fights Azir. A flashback shows Azir's citizens were angry that he showed favoritism to elves while his father Belgan encouraged him to marry Raniya to unite their races. The citizens rioted and killed Belgan, making him conclude he needs power to subjugate everyone so that they can be united under his rule. A mysterious man named Vidan hypnotized him into thinking he was his butler and gave him a seed. As the fight continues, Azir summons his sand monster, but Lowji takes it on. Azir freezes time again, but Lowji's anti-magic sword lets him resist it, then Yihdra deduces that Azir is really controlling the sand on everyone to freeze them. Tōgo knocks Azir down and lectures him to work together to unite the people instead of being a tyrant. Azir's seed consumes him and he hurls several stone blocks at the party, but Tōgo destroys them with the Victory Kizuna Buster. Azir screams for help as the seed turns him into a sandstorm headed for Sun Forest. Tōgo summons the Maximum Kizuna Kaiser, and with the whole party it is at 100% power, to intercept. After the credits, the origin stories of the Kizuna Five are told. ||||||
