His name is Masika, Masika means "born during rain". His Mother named him that because he was born during a horrible storm. The storm was so bad that it destroyed most of his home. He is a full demon but can conceal his demon form. In this picture there is more of himself and not of the demon. This is because the picture is his sanity bar. If the demon is closer to him it can take over him, and he will change into his demon form.
But like werewolves he has no control over his actions when he is taken over. He has a permanent tear stains on his cheeks because of the first time he turned. When he first turned he killed his mother horribly and dressed her up normally. So when he turned back he thought his mom was ok, because when she is happy she wears a red sundress. But as he walked around to face her he was horrified to see her dead with blood red tears staining her face.
That's why in the picture the demon has blood red tears. It wants him to suffer and remember what he did. That makes it easier to take over him. This also helps the demon because every time he reminds Masika of his mother he is more dangerous in his demon form. Thus giving the demon more power. But this demon can only take over Masika for a day and five hours.
As a demon Masika/Inferno (name of demon), he has the power to summon shadows. He can make them turn into his preys worst nightmare. He also has the power to summon the undead.
