Age: Unknown (around 18)

Familial situation: He doesn't live with his parents. Nothing is known about his mother, except that she was an alien. His father kicked him out of the house when he was a child. He is now unwillingly married to Fylee, making him the brother-in-law of Yue.

Occupation: Soldier

Special notes: He has violet cat eyes and pale blue hair. His facial skin is of a "normal" color, but a metallic necklace marked a radical color changing: his body is of a purple color with darker purple lines running over it. He usually wears turtle necks, long sleeves and gloves to hide it, but was caught in pyjamas by Daiya.

Character's psychology: He refuses to talk about his past because it is too painful for him to think about it and because he is afraid to lose the only friend he ever had; Daiya. It seems he was right when we see how she reacted to her discovery...
Eyro has problems accepting his 'difference'. He doesn't really denies it, but tries to forget it (covering the purple skin and refusing to talk about himself) and to live as if he was 'normal'. However, his alien instincts are coming up as he's becoming an adult and he cannot keep denying them forever. When Daiya finally learns about them, he's hurt by her reaction of fear and hides from her, not wanting to cause her any more shocks and unsure about what to tell her. He knows he's an alien, but couldn't explain why he's on Earth. Deep inside, he tells himself he knew this would eventually happen and that having relationships with people cannot work out well for him. Eventually, they'll be scared and will run away, or will be mad and kick him out, like his father did.
When the aliens come to take him to their war, something he doesn't know or care about, he follows with no objection, having nothing to do on Earth anymore, but cannot leave before telling Daiya and seeing her one last time. Acting cold and distant during their short reunion, he's hiding the pain of losing her. By giving her the necklace, he's proving his feelings and care for her, showing he does regret he has to leave. When he realises she doesn't reject him despite his true nature, the pain is greater but he can't move back and stay with her.
Eyro is a constantly lonely person. Even with hybrids like him he won't pair up and stay apart. He doesn't bound with his fiancée for this reason, but also because it feels as a betrayal toward Daiya, who was the only positive element in his emotionnal life and is now a bittersweet memory. He doesn't want to break this unique relationship, especially with someone who doesn't even want to be intimate with him.
He eventually becomes one of the best recrutes of the Army. Hybrids are powerful, less than fully blooded aliens, but still powerful; Eyro develops his potential more than the average hybrids by hidding his feelings. Training and fighting is a good way to stop thinking and not having to talk, but also to not have to spend time with Fylee.
He doesn't feel concern about the war and will fight only because he is told to. He doesn't feel like he has any other purpose and will therefore accept this as his faith, even if he doesn't really believe in it. At that time, Eyro is cracking inside: he has lost Daiya, is married with someone he cannot fall in love with and is obliged to go to a war he doesn't care about... However distant he acts, he's worry and scared inside. He'd like to run from the war and not have to fight. But he doesn't have anything else.
He'd want Fylee to love him, to find in her a remain of Daiya. But she's nothing like the young girl and it hurts him to unconsciously compare them and be disappointed all the time. The only thing uniting them is, strangely enough, sex. Sex is just like a fight for them: it's physical, there's no word to be said, only a relief to reach. By this union of their bodies, Eyro can find a little part of what he's grieving for: love.
