Aisho Dainenjiyama

Aisho is a 29 years old rock human.Rock humans are a silicon-based lifeform similar to humans and living alongside them, who possess unnatural abilities such as hardening their skin into stone or endure extreme temperatures; they also can enter a state of hybernation, during which their bodily functions slow to a crawl and they sleep for an extended periods of time. Rock humans possess a very low to none social drive, avoiding connections that don't benefit them directly, and lacking empathy or attachment towards others. Aisho seems to be an exception to that rule, however, possessing the ability to get attached to others and making irrational decisions due to that.

Aisho is emotional, nervous, paranoid and slightly naive. He has a heart condition, his heart having an abnormally increased rhythm during stressful situations. Aisho tends to overreact to stuff when he's nervous. He's less tough than most rock humans, although still can be violent. He tries his best to keep a stoic facade to hide his softness. Has been betrayed in the past by the person he loved. He has a good reason to be paranoid, since his naivete and his softer personality can put him in danger.

Aisho tries to keep a stoic facade, but in fact he is very nervous and paranoid most of the time. When he is upset, he tends to notice and overreact to the smallest of things and start to act irrationally. He is also easily frightened and intimidated by enemies he can not see. He can get so nervous that he will briefly experience flashbacks to previous traumatic times or experiences. He is less capable of controlling his rock physiology, for example, not being able to wake up for at least a month every time he goes into hybernation. It is a combination of this fact and his naivete that led him to misplace his trust in a previous lover who cheated on him and sold his house while he slept in his rock form.
