Tetsujin

**Tetsujin** is the last Kaikishi in the Samurai Rabbit: The Usagi Chronicles Netflix series.

## History

The arrival of Yuichi Usagi in Neo Edo causes the Ki-stone's power to flicker, which causes Tetsujin to feel worried about it. Later, Usagi, chased by Gen and Kitsune breaks into the Kaikishi temple from underground, causing some of the priceless vases there to be broken. This makes Chizu furious, who chases them into the center part of the temple, where Tetsujin accosts the group. He introduces himself as the last Kaikishi in existence, and just after he asks why Usagi resembles Miyamoto Usagi, he learns that Usagi is his descendent. At that moment, Tetsujin realizes that Usagi is why the Ki-stone is acting up, and when Usagi touches it, he tries to stop him, only to be affected by the stone's power.

Usagi touching the Ki-stone caused the Yokai inside to be released into the world and made Tetsujin's waveform rotate through a higher dimension. At that moment, the Ki-stone starts to light up and flicker, which Tetsujin translates as it has decided to awaken the Shrine of the Kaikishi. When Usagi chooses a weapon from the selection, he chooses the Yo-yo, which Tetsujin congratulates. Just then Lord Kogane accompanied by the Keisatsu demand that Usagi come out immediately. Outside, Lord Kogane demands that Usagi come forth, and when he does, Usagi learns of his ancestor's scornful past and is arrested. After Gen, Kitsune, and Chizu leave the temple, Tetsujin amuses himself by feeling inside of his body.

Eventually, under the orders of Lady Fuwa, Chizu tries to steal the scroll of secrets from the temple, but in her first attempt, she causes a scene that attracts Tetsujin's attention. Curious to know why she was there, Chizu tells Tetsujin that she wants him to make a new horn for Gen, who lost his old one. Tetsujin does this and gives it to him after they free Lord Kogane from being possessed by a hat Yokai.

When Usagi managed to capture the Yokai Hakai to convince Karasu-Tengu to become his sensei, Tetsujin is seen meditating by the Ki-stone. Once Usagi returned it to the Ki-stone, Ninjas led by Lady Fuwa surround the inside of the temple, and Chizu is revealed to be a part of them.

In the ensuing battle, Chizu betrays the ninjas and fights against them. Tetsujin also helps in the battle, but is dazed by a bomb. With Usagi and his friends captured, Tetsujin warns the ninjas that they cannot control the Ki-stone. However, they don't heed Tetsujin's warning, and following Lady Fuwa's orders, they try to remove the Ki-stone from its mantle, only to be blown away by its power. Amused by this, Tetsujin reminds them that it's been said never to touch the Ki-stone. After this, Usagi and his group deal with the ninjas, causing them to flee and making Chizu explain herself to them all. Hearing Chizu's explanation makes Tetsujin give a farming metaphor that resonates with Usagi. Tetsujin then reveals that the Scroll of Secrets is a fake thing he created to fool Lady Fuwa into thinking there's a way to move the Ki-stone. In truth, it's 100% immovable as it's locked to the Earth's magnetic field and then tries to console Chizu about her betrayal to everyone, but is inconsolable. When everyone walks out on Chizu, Tetsujin hands her a broom, and although he forgives her, he firmly states that she'll receive no New Year's bonus. He also notes that Kitsune will be challenging to receive her forgiveness and suggests she find her and bring her a present.

Afterward, Tetsujin watches as Usagi returns Sakuran to the Ki-stone and then gets another flashback of his ancestor. Usagi tells Tetsujin of what he witnessed from the Ki-stone and claims his ancestor didn't kill the Shogun in the past. Tetsujin then gives a proverb about the history and tries to give an example of his previous relationship with Lady Fuwa, but Usagi leaves before he can begin.

Kitsune visits the Ki-stone Temple to recharge the Ashibasha battery, and after Tetsujin sets it up to be recharged, he shows her his Taiko Drums. Initially, she has no interest in it, but becomes addicted to being flung around by its propulsive shockwaves. They would later set up a target for Kitsune to land on.

Usagi visits the Ki-stone temple accompanied by Hana and Kana, who Usagi introduces to Tetsujin, but also mentions that Kana is really Giman. One of the Yokai that Karasu-Tengu ordered Usagi to capture and return to the Ki-stone so she could become his sensei, but he cannot bring himself to do. The Ki-stone starts to flicker, and Tetsujin claims that the Ki-stone wants to show him something. However, after seeing the flashback, Usagi realizes that his ancestor was the villain he was portrayed as. Despite Tetsujin's pleas for Usagi to watch the rest of what the Ki-stone had to show him, he refuses to see it.

Afterward, Kagehito arrives at the Ki-stone temple with the Clavis in hand. The Ki-stone grants Tetsujin some of its power to help prevent Kagehito from attaching the Clavis onto it. He does this long enough until Usagi's group arrives, but he lets the group continue fighting against Kagehito on the streets because of his severe exhaustion. However, when Kagehito returns to the temple, he fails to stop Kagehito from the Ki-stone, who manages to attach it to the Ki-stone. After he does, Kagehito broken out of his mind control spell and warns everyone about their impending doom by the hands of the Makkine as a giant gate opens in the sky. While Tetsujin warns that the Ki-stone is trying its hardest to keep the gate closed. Usagi tries to rip off the Clavis off of the Ki-stone, but he doesn't listen and does anyway only to trigger another flashback that everyone in Neo-Edo witnesses. The flashback itself, proves his ancestor's innocence. From there, Tetsujin groups with Chizu to locate Yuichi's Aunt so they can get retrieve the gem on the hilt of Edgewing. They search the arcade and not only do they not find her their, but Tetsujin terrifies the worker their with his incorperal form.

Eventually, machines called Warbotto invade the temple and Usagi's group all fight and win against the invaders. Tetsujin would later fling Usagi from his Taiko drums as a form of entertainment.
