I have like 5 characters but I will go with the only one that is shown in the comic now lmao.
Honestly remembering the description I wrote of this character, he reminds me much of the difference between the Opening song to Death Parade and the anime itself. By that I thought he was going to be a cheerful character (the Opening with Decim dancing cheerfully as everyone else) but I ended up realizing that there is no clear reason for the character to be that cheerful (Decim in the anime is something else, let me tell you.).
That is sort of a loose correspondence but yeah.
Name: Yan, just Yan.
Age: Honestly I don't know where to start counting his age, though. From his first awakening in manufacture? 57. Starting a new life after being bought and upgraded? 27. Depends on how you look at it
Favourite color: Is it possible for a robot to have a favourite color? But I guess as he has emotions he can pick a favorite. His favorite color would be the one of his hair, a weird black with a tint leaning more to blue.
Quirks: He tends to pick a person and care for them, only them. He also trusts that single person with his whole robotic heart, so watch out.
Personality: As said, I expected him to be more of a happier person, his design came up from the radio when I was driving to my grandparent's house. Actually all five characters were modeled by 4 songs I heard on the radio that day, the song Natural first played before the four songs. His song was "Rise" by Jonas Blue. But again maybe 3 characters actually shaped to their song.
But talking about his personality; he is mature, even from his modeling background he never acquired the usual snark attitude other models had, must've been the caretaker code. He is loyal to anyone and knows his place. His relaxed part is really only present upon request, but even then he isn't too relaxed. He still cares a lot.
Now I feel like I did spoil a lot about him since it feels like some of this isn't even in his description in the chapter. Ouch.
