i think that aira’s family would be quite normal compared to other people’s backgrounds? not notably rich or anything, just a regular middle-class household… maybe a little more on the wealthy side for aira to have the money to save up and purchase a lot of idol merch + being able to send their son to an idol academy (despite aira’s parents being against him wanting to become an idol too, they are still paying the tuition so…) but i’d just say aira has a very normal and typical family life which i think is important because of his relationship with other characters with not-so-typical family backgrounds (namely alkaloid, but also kohaku in a sense)

having aira as someone with a more normal background compared to the rest of alkaloid highlights his insecurities even more so, because the people he’s friends with stand out in such a way that aira feels like he doesn’t in comparison. he’s kind of insecure about standing out because of his appearance but in actuality, his life isn’t all that interesting because he’s simply just a massive idol fan and relatively mediocre in ability, nothing like the expectations people have of him. so i can’t really imagine aira having anything else but a regular family that loves him. in main story, there’s a scene where aira mentions how his family doesn’t really support his idol dreams, and wants him pursue a ‘proper’ career rather than trying to become an idol which is incredibly hard and risky for all sorts of reasons, and that scene resonates with me a lot… it shows that his family loves and cares about him, and because they do so, they want him to pursue something ‘safe’ even if it doesn’t particularly align with aira’s own hopes and dreams… and how despite that familial pressure, aira pushes through because he loves idols so much, he wants to become one even if he believes he isn’t anything special. it’s a small part of aira’s character that i really love although it’s not mentioned often because his family life isn’t really all that noteworthy… so i think him having a regular family background is actually pretty important to his character building! it’s also charming to me so hghhgh

sorry for the random rant about aira’s family background it’s actually a part of his character that means a lot to me… ahaha

his idol collection is pretty impressive though i must say, he’s so dedicated… imagine the years of saving and collecting he must’ve done… he should have the most impressive itabags ever
