Doku Nisshoku

Doku Nisshoku is a shinobi that is in Karuto and Amai's class in the Ninja Academy.

## Background

After Mitsuki’s twentieth birthday, when Orochimaru realized that it’s time to make a new version of Mitsuki, one who could hopefully achieve powers greater than her “parent.” During the cloning process, Orochimaru was able to use Yamato’s, who recently died, and Hashirama’s cells to transfer Wood Release to her. He also synthetically created a dojutsu for her, which he deemed the “Netsugan”, though he himself admitted that it wasn’t nearly as powerful as any bloodline dojutsu. Doku explains that the process of eye and cell infusion is extremely painful, and though Orochimaru is her creator, he’ll always be a monster to her. For the first six years of her life, she lived in a laboratory with no human interactions other than Orochimaru. It all took a turn when one of Orochimaru’s assistants, Kokuzoku, planned a coup to take control of the snake wielder’s lab. One afternoon, after Orochimaru left, Kokuzoku started breaking all of Orochimaru’s stuff. Once the “children” noticed, Kokuzoku started smashing their tubes, killing them. Orochimaru came in and killed his former assistant, but not before all of Doku’s brothers and sisters were killed.

## Personality

Due to her background, Doku acts erratic, confusing, suspicious, and as Amai describes it, "could be a huge threat."  She has shown to be socially awkward and inappropriate on multiple occasions, and doesn't appear to have any understanding of human nature or behavior. Even Iwabee wondered who or what she is, and what she could be hiding. She is also shown to be quite sadistic, as she doesn't hesitate to attack Amai after he yells at her.

## Abilities

Being very mysterious, the full extent of Doku's power is currently unknown. However, she was able to fight and eventually kill a chunin-level mercenary while in the academy, which is a testament to her abilities. She also has multiple kekkei genkais, including the first Hokage's devastating wood release.

### Ninjutsu

Doku can use a jutsu to turn invisible, and Amai points out that it must be a chunin or jonin-level technique that shouldn't be learned by academy students. She can also use water release to send out a barrage of high-pressure water bullets strong enough to shatter rock. Her affinity is Lightning release, and she can summon bullet-shaped entities made out of electricity that can follow the enemy. She can also use the versatile kekkei genkai wood release as a result of Orochimaru's experimentation.

### Kenjutsu

Doku is very skilled with her sword, and was able to swiftly corner even Amai, a Uchiha and weapons prodigy, with her sword. Like many other lightning release users, she can infuse electricity into her sword to increase its range and make it more lethal.

### Nature Transformations

Doku's affinity is lightning release, and she can infuse her electric-based chakra into her sword to make it stronger. She can also use water release, as shown in her scuffle with Amai, which implies that she is very skilled with her chakra management. She can also use the versatile kekkei genkai wood release as a result of Orochimaru's experimentation.

## New Generation

### Academy Training Arc

Doku first appears hiding behind Karuto and Amai for an unknown reason. She then reveals herself to them and quickly befriends Karuto, much to Amai's annoyance. Later, at the academy, when Iwabee asks the trio to talk about themselves, Doku refuses, much to everyone's confusion. This annoys Amai, who yells at Doku. She responds by holding a lightning-infused sword to his neck, but she finds out it's just a shadow clone. He then uses Fire Style: Fireball Jutsu at her, and she responds with Water Style: Sea Snake Barrage, which overpowers Amai. Iwabee breaks up the fighting, and makes them both apologize, and they do, albeit grudgingly.

Later, Iwabee sends them home, but not before telling them to practice their shadow clones. Amai and Karuto then see Doku practicing her jutsu in the forest. in the process of spying on her. Amai asks her what she’s doing, and she explains that she’s perfecting her newly created jutsu, Lightning Style: Viper Strike. Amai asks her why she’s able to use two nature transformations, and she says that she’s just incredibly skilled in ninjutsu. This angers Amai, who tells her that she’s just dangerous. She shrugs and walks away.

Doku is later seen near the outskirts of Konoha, near a forest. The two eventually find her, and climb up in the trees above. However, Doku senses them with her dojutsu, which shocks Amai. Surprised, he jumps down with a kunai in his hand, and Karuto and one of his shadow clones follow. Doku takes out her sword and points it at Amai, who asks her who she’s a spy for. She claims that she isn’t a spy, and tells Karuto, who’s behind her with a kunai at her neck, that she can see him. Amai asks her where she lives, and suddenly Karuto senses something rapidly approaching out of the ground. He warns Amai, and the two move out of the way before wood comes out of the earth. Amai is horrified that Doku has the first hokage’s kekkei genkai, and asks her what she is. However, she senses Karuto attacking her with her dojutsu, and blocks it. However, it’s a trap, and Amai uses the opening to cast a genjutsu with his sharingan. Doku then wakes up in a secret room down in the subway, where she finds out she is restrained by metal wire. As they start asking her questions, she sees something behind them, and when it gets closer, she realizes that the two mercenaries are coming straight for them.

Doku warns the two about the attackers. While Amai thinks that it’s just a distraction, Karuto activates his Byakugan and sees that Doku is telling them the truth. They all then turn around, and Amai asks why they’re here, while activating his Sharingan. The bigger one seems impressed that there’s a Uchiha, and he introduces himself as Mujona. The smaller one says that he’s Zankoku, and explains that years ago, they were Konoha shinobi, and due to a mission where they had to sacrifice their teammate to succeed, they became shunned by their village. They then became assassins-for-hire, and believe that by kidnapping the Hokage’s grandchildren, they will get the money and notoriety to start up again. They then tell Doku she’s free to go, but she refuses to, and stays there to protect the two. Mujona draws his sword, and he and Doku start swordfighting. Meanwhile, near the other side of the subway, Doku and Mujona clash swords on the train tracks. Doku uses her genjutsu to dodge Mujona’s next attack, but he takes out three swords, holding two in his arms and one in his mouth. This is too much for Doku to handle, and while she is dodging one attack, she lets her guard down and is sliced in half by Mujona. Mujona is happy that Doku is out of the way, but he realizes it’s just a wood clone. Doku then uses wood style to create branches out of the floor which she climbs, allowing her to gain the higher ground. However, Mujona climbs up the branches, and slashes the one holding Doku. She quickly uses her dojutsu to grab onto a still-growing root, but finds Mujona right above her, who stabs her fingers off. He explains that if she left earlier, she could’ve gotten away, but now that they found out about her wood style, she’s another target. Mujona notices Zankoku’s dead body, and vows to get revenge. He then points a sword at each of the three academy students, and tells them that the next attack will finish off all three of them at the same time. Mujona shifts to his Triple Blade Technique stance, and starts infusing his blades with chakra. Karuto asks Amai what’s going on, but notices that Amai’s using his Sharingan. He also sees Doku using her dojutsu, and he turns on his Byakugan too. He then sees a monstrous amount of chakra being built up in the swords, and realizes that even a high-level jonin would be instantly killed by a move like that. Doku uses Wood Style: Tree Wall Barrier to block them, but is shocked that Mujona cuts through like “ribbons.” Amai asks Doku for her sword, and she reluctantly gives it to him, stating that it’s “suicide” to face Mujona in this state. However, Amai activates his sharingan, which allows Amai to run at him, The two clash swords, and Amai ducks in time to avoid his other sword. Amai takes out a kunai, which Mujona blocks, and uses the opening to attack with Doku’s sword. However, Mujona uses the sword in his mouth to counter, breaking Doku’s sword into two and rendering it useless. Just as he is about to kill Amai, Karuto throws a kunai at Mujona. However, he isn’t fazed, and uses the Guillotine Technique to kill Amai. However, he realizes that it’s just substitution, but it’s covered in paper bombs. Amai then uses Fireball Jutsu to detonate the bombs, but Mujona escapes. Karuto then uses Gentle Fist to cut his chakra, and Doku uses wood style to form many trees which pin him down. Amai then uses Fireball Jutsu to burn the trees down, killing Mujona. Amai then apologizes to Doku, noting that even though she could’ve gotten away, she stayed and tried to protect them. Doku then states that it’d be for the best if she shared her story, and warns them to get ready.

## Trivia

* "Doku" literally translates to "venom", while "Nisshoku" translates to "eclipse"
	+ "Venom" might reference how Karuto and Amai originally thought that she was an enemy, and her snake-like jutsus
