23 : Tenko Shimura: Origin
During the fight we get to see the initial origins of Shigaraki, he finally remembers the memories that eluded him for so long. Nana's decision of giving her kid away to keep him safe severely backfired, and the trauma was passed along to the next generation. It seems he held on to the grudge of being abandoned and thought heroes put their families aside in order to save the rest of the world, so naturally: he banned all sorts of hero talk in their home. Often lashing out at Tenko (Shigaraki) for having dreams of being a hero. I am not really a fan of sympathizing with villains, but these types of storylines often break my heart. The poor kid was so emotionally abused that he ended up killing his own family when his power manifested. The puppy was the one that hurt the most, not going to lie. It was pretty heart-wrenching, to be honest.
23 : Tenko Shimura: Origin
My Hero Academia is based on the manga series of the same name by Kouhei Horikoshi, and the anime is produced by Studio Bones, a studio that is counted among the absolute top tier of all anime studios. Studio Bones is also known for working on anime like Full Metal Alchemist Brotherhood and Mob Psycho, so you know that My Hero Academia is in outstanding company. Season 5 is directed by Kenji Nagasaki and Masahiro Mukai. If you want to catch up on our My Hero Academia reviews, you can read our review of Season 5 Episode 22 here. This episode is also known as Boku No Hero Academia Season 5 Episode 23 in original Japanese.
As its name suggests, the episode was based around the origin story of Tenko Shimura or Tomura Shigaraki as we know him. We have already got a hint from a prior episode, but his situation was bloody and heartbreaking. You get the feeling the All for One lied to young Tenko about what happened, but the reality of the situation was much more than one might anticipate. In fact, this episode was, bar none, the darkest episode of My Hero Academia anyone has ever seen.
But at the same time, the theory that Shigaraki wields Deku's original quirk could hold the secret to how Deku will ultimately triumph over the League of Villains and foil All For One's plans. Now it's been confirmed that quirks can be transferred between people, the My Hero Academia anime has also implied and outright revealed that quirks carry traces of their previous users. This is shown to be the case with Deku's Black Whip quirk and would theoretically apply to any other powers All For One has stolen and transferred to other people throughout his evil dealings.
If Deku was the original wielder of Shigaraki's quirk Decay, this would also imply that some trace of Deku is left in the power, which could give My Hero Academia's protagonist an edge over the leader of the League of Villains. It's unclear how exactly this could play out, but it's possible that Deku could exert some control over Decay even while Shigaraki is wielding it, which could be the key to the antagonist's defeat. By the ending of My Hero Academia's anime, if Deku really did wield Decay first, he could learn how to tap into the quirk and gain a unique advantage over Shigaraki that nobody else has.
Interestingly, when Tenko was at the age of five, he bore a striking resemblance to Izuku Midoriya, with his blue hair originally being dark black in color, as well as having gray eyes instead of red. He also had dried patches of skin around his eyes, though his lips were shown to be healthy in appearance. After his Quirk manifested, his appearance changed giving him a wrinkled face, his hair color to a more light blue, and his eyes slowly turned to red after the first manifestation.
Each pair of these hands originally belonged to an individual killed by Tomura during the time his Quirk first manifested: the one on his neck is his mother's; on his arms, his grandfather's; on his forearms, his grandmother's; on his wrists, his sister's; and the ones on his chest and shoulders are from two unnamed street punks he killed.
During the events of My Hero Academia: Heroes: Rising, Tomura wore a dark red trench coat along with the brace for his left hand, although he is depicted with his original clothes and hair color (likely due to the anime staff not having an adaptation of his updated design for him at the time).
When Erasure was undone, Tomura's body exploded, undoing the metamorphosis and resulting in his original personality re-emerging from within, molting out of the defense form and reverting his body back to his prime state.
Despite that, Tomura affirms that he and Tenko both have the same goal upon reclaiming his body from All For One: the destruction of hero society. "Tenko" was representative of his origin that he implanted deep within All For One's vestige as a means of winning back control of himself and the All For One Quirk. He also reveals at this time that he has no need for One For All, and that his previous obsession with stealing it was just a forced extension of his master's will. Even if a part of him is still in pain, Tomura sees the rest of the world as no different from the abusive house he grew up in and will stop at nothing to eradicate everything associated with it.
Even when the vestige of All For One was taking control of Tomura's body, Tomura's willpower never wavered from anything, even from his master. His strong willpower was so immense that he hid his own core deep within his own soul, and without All For One noticing, he has been able to reclaim himself from the inside and out, following the path toward his origin as he continues down his dark crusade to destroy everything that created the abusive house he lived in.
Decay (崩 (ほう) 壊 (かい) , Hōkai?): Tomura's original Quirk allows him to disintegrate whatever he touches with all five fingers. It will take effect whether the target is organic or not. The disintegration spreads quickly and will spread through the victim's whole body if they don't amputate the decaying body part. His Quirk can even spread beyond what he's touching, allowing him to disintegrate large groups of enemies instantly.
All For One (オールフォーワン, Ōru Fō Wan?): Tomura's second Quirk is the original version of All For One used by his master. It allows him to steal other people's Quirks and use them as his own. Just like its counterpart Quirk One For All, this Quirk contains the vestigial will and consciousness of its previous wielder. However unlike One For All, the vestigial will of its previous wielder seeks to usurp Tomura's body using his negative emotions such as anger and hatred as a catalyst. This makes the relation between past and present users more parasitic than symbiotic unlike its counterpart, thus allowing the elder Shigaraki's vestigial consciousness to take over instead. However, with enough willpower, Tomura is able to regain control of both his body and the Quirk itself. 041b061a72
