|Debut||330. Gathering Under The Banner Of Rebellion|
|Final Appearance||381. Converging on Despair|
Ryuuji was a hunter from Hiroshima, who responded to Kurono's and Reika's call, to join the Tokyo team and fight against the invading aliens. He explicitly stated that he is not a fan of Reika and that the reason for joining the fight was because he supports their cause. Ryuuji seems to be more of a melee fighter according to chapter 338 though that may just be because he doesn't have a weapon. He also is an admitted virgin. He later dies, saving Kei from Eeva Gund. Dying with a smile on his face--saying that he has no regrets. He is soon revived and transfered back home, however, after Kurono and Kato defeat Gund.
Personality and Fighting Style Edit
He is fairly stoic and quiet. He has a deep sense of justice, joining Kei and other members of the Katastrophe team to assist Kei in saving the captured humans. He appears to not have an active interest in women, inadvertently admitting that he is a virgin to the other members which ultimately ends up with him in his silent embarassment.
He is a skilled fighter, preferring the use of a sword which he is skilled at using, dispatching many aliens. He also uses the Gantz guns occasionally. The fact he is still alive thus far is a testament to his skills. He seems quite adepts at using close up melee as a last resort, in doing so he was able to keep up with the agile Eeva Gund for a short while, repelling his attempted attacks with his own. Despite this, he was no match.
