Todoroki is the last Demon to join the main cast of the show. Despite that he is older than Josh at 18, he is still very much a novice. A green Demon, both in color & appearance, he is still learning how the world around him works. Having only just become an independent Demon during his introduction, he sticks close to Hibiki & Ibuki & looks to them for guidance. Eager to do please his master but do things in his own style, he often meets conflicting points of views from others, but continues on with what he believes is "his" way. Todoroki was the last of the main series' Demons to be introduced. He was first seen in episode 12 greeting Josh at a hospital. He later returned with his master, Zanki, to fend off a pair of Makamou. Originally he was to be the next Slashing Demon, but declined the offer from his master so that he could create his own legacy as the Roaring Demon.

Of the three main Demons, Todoroki is the youngest, thus he is the most childish. He still acts like a novice with many Demon matters & enjoys the simple things that life has to offer him. He is also one of the more clumsy characters on the show, this trait often leads to problems both in & out of battle. Even though often misguided, Todoroki will stand by his friends no matter what comes their way.

When he became a solo Demon, Zanki had some trouble accepting the way that he fought the Demon & his "cleansing" of the battlefield. Eventually Zanki came to accept that this was Todoroki's way of being a Demon. During the summer of training arc, Todoroki saw Hibiki as a teacher, & Hibiki offered Todoroki guidance on being a solo Demon & the new challenges that life would bring him now that he had no master.

Todoroki soon came to find fighting the Demons on his own to be a tough challenge. In response to this, Zanki returned to be his supporter & offer advice whenever he could.

Throughout the series, Todoroki had a crush on Monday Flores. One day he gathers enough courage to asks her out on a date on her birthday. The date goes horribly wrong for Todoroki, he makes a fool of himself & ruins her gift. Monday became upset with Todoroki & the two were distant with each other for a while.

Late in the series after the Shuki incident, Todoroki was literally stepped on by a giant Makamou. This left the others questioning whether or not Todoroki would ever be able to transform again. Zanki feared this would cause Todoroki to go into a state of depression, indeed it does. Zanki believes that Todoroki was born to be a Demon & that he knows no other way of life.

Eventually Zanki meets his end, but puts a spell on his soul to allow him to remain on earth until Todoroki no longer needs him. It was around this time that Monday & Todoroki became friends again, even though she offered her help to teach him how to walk again, Todoroki declined. Even when Zanki helped him out, Todoroki said he wanted to do it on his own, otherwise he would never be able to show that he is an independent warrior.

Todoroki learns to walk again & rushes into Zanki's final battle, the both make quick work of a large number of Makamou and soon it is time for Zanki to pass on. Todoroki & Zanki have one final cleansing session as Todoroki pays his final respects to his former master. After these events, Todoroki has finally become the man that he always wanted to be.

Many fans agree that Todoroki was the most changed character of the entire series. Going from a new Demon, still worried about his skills & unsure about his ability to live in the world on his own to a confident man who works well with others & trusts in his own strength.

  • Demon Fighting Technique: Demon Claw: Forms claws from his hands to stab & slash at Makamou. These claws are nearly unbreakable, thus making them one of Roaring Demon's most useful weapons.

Sound Attack Finishers

Sound Attack Slash: Thunderbolt Exciting Quake: Roaring Demon stabs his weapon into the body of a large Makamou & changes it into its guitar form. He plays the guitar in a wild & fast manner.
