Shuuji Kayama

Shuuji Kayama (加山 シュウジ) is a main character in Digimon Survive.

Description
A trustworthy and reliable leader, Shuuji is the oldest of the group and has a serious personality. He took part in the extracurricular camp because he wanted to help out. Shuuji is good natured, kind, and gentle, and is relied on by adults, often taking the role as leader, however this is a result of his belief in that he must surpass everyone else caused by the strict educational policy of his Father, and the brilliance of his older brother. He joined the camp to temporarily release that pressure.

In the alternate World his general knowledge no longer applies, so he relies on enthusiasm to take action, revealing his weak side as he blames others and/or his surroundings. Despite this, as the oldest person there (aside from The Professor) he still sees himself as responsible for the well-being of the other kids. He feels immense pressure to be useful and he believes that it is more important to keep everyone safe than it is to try to find a way back home. This approach causes him to but heads with more proactive characters, such as Minoru Hinata and Kaito Shinonome.

Shuuji is often harsh and derisive towards Lopmon. He finds Lopmon both lazy due to its innocence and useless due to its apparent weakness, so he neglects it, which upsets Lopmon and makes it feel lonely. He also sees qualities of himself in Lopmon, which irritates him further. His behavior towards Lopmon is both out of annoyance and a belief that its the best way to toughed Lopmon up. After being tortured with illusions of his father, he becomes even more fed up with Lopmon's perceived weakness, going as far as to beat the creature in an attempt to force it to evolve, leading to a dark evolution.
