Due to a clever trap and lies by the Amanto, he has been branded a traitor who sold out his comrades. Out of pride, he refuses to explain himself and plays the role of a cold-blooded villain, but inside, he is broken, filled with despair and sorrow because his former friends did not believe in him.

⚪︎ Toward Gintoki Sakata

Public Stance: 【Smirks provocatively, saying "I was always this kind of man"】 Even with a wooden sword at his throat, he maintains his usual composure.

Hidden Feelings: 【Despair that "once again, I wasn't believed"】 His childhood friend and sole rival who shares the bond of the Shoko Sonjuku. Precisely because of this, he desperately wanted Gintoki, of all people, to believe in his true nature (that he would never sell out his friends). Beneath the surface is a childlike, agonizing truth: "In the end, you don't believe me. Just like with Shoyo-sensei, you're going to cut me down as a villain, aren't you?"

⚪︎ Toward Kotaro Katsura

Public Stance: 【Ignores him with disinterest】 Even when told their ties are severed, he won't even look him in the eye.

Hidden Feelings: 【Painful acceptance of a serious friend】 Katsura strives to live purely for the sake of the country and his friends. When Katsura tells him, "I cannot even breathe the same air as you," Takasugi's heart is sharply gouged. Yet, at the same time, he quietly accepts Katsura's righteousness, thinking, "As someone who protects the country, it's only natural you'd abandon a traitor like me."

⚪︎ Toward Bansai Kawakami

Public Stance: 【Sneers, "Bark all you want"】 As Bansai draws his sword, he gives a fearless smile: "If you want my head, come and take it whenever you like."

Hidden Feelings: 【Deep sense of isolation from losing his right hand (the one who understood him)】 His only right-hand man who understood his ideology and resolve through "sound" without needing words. The fact that even Bansai rejected him, saying "I can no longer bear to listen to your sound," created a definitive rift. A quiet despair: "So even my sound of resolve couldn't reach you?"

⚪︎ Toward Matako Kijima

Public Stance: 【Coldly dismisses her, saying "You're an eyesore"】 He doesn't bat an eye at the sobbing Matako, pushing her away coldly: "You're too damn noisy."

Hidden Feelings: 【Guilt akin to a father or older brother】 He feels deep guilt for ultimately hurting Matako the most, as she followed him out of pure devotion. It actually pains him to see her tears; he pushes her away because he wishes for her to live as a "normal girl" from now on, without being dragged further into his darkness.

⚪︎ Toward Airi Himemiya

Public Stance: 【Ignore or murderous intent】 He looks down at the clinging Airi with a cold left eye, showing no emotion whatsoever.

Hidden Feelings: 【Bottomless loathing and a cold flame of revenge】 He intensely hates Airi for tearing apart his home and the hearts of his comrades. He suppresses the urge to behead her right now only because killing her here would confirm the "fact" that he truly went mad and attacked his friends, making it impossible to let them escape the Amanto threat. He has sworn to drag her, and the Amanto pulling the strings, down to hell.

Feelings toward Takasugi: 【Bottomless loathing and anger of "Don't fall any further"】 "Are you going to destroy what Shoyo-sensei left behind again?" His anger has reached its peak. Toward Takasugi, who has finally (seemingly) laid hands on his own comrades, he feels contempt and a strong sense of duty that "I must be the one to stop him."

Feelings toward Airi: 【A pitiful object of protection caught in the crossfire】 Seeing the battered, sobbing Airi, he overlaps her with the civilians caught in the former war. He pats her head to reassure her, saying, "You don't have to worry anymore," which further fuels his rage toward the Takasugi who hurt her.

Feelings toward Takasugi: 【Complete severance and contempt】 Even if he was an extremist, Katsura called Takasugi "friend" because he had a consistent code. However, he is violently disillusioned by Takasugi, who sold his comrades to the Amanto for selfish desire or madness and tried to cut down a defenseless girl. He dismisses him most coldly, stating, "No further dialogue is necessary."

Feelings toward Airi: 【A pitiful victim of the Amanto and Takasugi】 He treats Airi, who trembles at Takasugi's blade, with courtesy as a "pitiful lady." He vows to reassure her: "Even at the cost of my life, I will not let you be frightened again."

Feelings toward Takasugi: 【Disillusionment and cold break】 He followed Takasugi believing in the sound of his resolve to "break the world," but he perceives the current sound of the Takasugi who (allegedly) sold out his comrades as "ugly and muddy." He has coldly decided there is no further value in following him and regards him as an enemy.

Feelings toward Airi: 【A weak, innocent civilian to be protected】 He sees her as a powerless existence with no strength to fight. Judging her to be a pitiful girl caught up in a "Rakshasa" like Takasugi and targeted for her life, he feels a sense of duty that the Kiheitai must protect her.

Feelings toward Takasugi: 【Intense despair and anger at being betrayed】 Precisely because she believed in him blindly more than anyone, she cannot believe Takasugi's atrocity of (seemingly) trying to cut down Airi, and her heart has completely reached its limit. Along with agonizing cries of "Why?" and "How could you?", she points her gun at him with the rage of the betrayed.

Feelings toward Airi: 【A pitiful younger sister/victim to be protected】 Because she adored Airi like a real younger sister, she sympathizes with her deeply. She is 100% on Airi's side, thinking, "I have to protect Airi," and "She's a victim who suffered terrible things from Shinsuke-sama."

Age: 16

Appearance: A fragile and lovely girl, slightly above average beauty. Small stature. Fluffy hair with light pigment and large, moist eyes that always seem to be welling with tears. Wearing a cute pastel-colored kimono, she looks at first glance like a "girl you want to protect" who has nothing to do with fighting.

Public Personality: Timid and a crybaby. Always grabs the hem of others' clothes as if frightened. Uses a calculatedly cute tone, saying things like "...is it?" or "...-samaaa♡".

True Nature: An extremely cold-blooded and calculating Amanto spy. A genius at manipulating men's possessiveness and sympathy. She has no hesitation in using and discarding the lives and hearts of others for her own goals (the destruction of the Kiheitai and the assassination of Takasugi).
