Do you have any head canons about Luna and Mana?
Yeah! These are the ones I have
They like playing with Hakkai a lot because he's more energetic then their brother (poor guy needs a break sometimes)
Mitsuya actually did teach them to not trust delinquent's (despite his friends being delinquent's he knows how dangerous some can be)
They both saw Draken as a second brother
For his birthday, Mitsuya frequently asked only for a hug from both of them which they happily gave him
When they get older, they spoil Mitsuya a lot on his birthday, something they couldn't do as kids.
They like Baji a lot too, especially when he gives them animal facts or manages to call a cat over.
Yasuda babysits them often
They have a secret handshake, not even Mitsuya knows it
After Draken's death, Luna tried to look after the house and Mana to give Mitsuya time to grieve.
They both brag a lot about their brother at their schools
If they ever met the Haitani brother's they would also call them "dumb face" which would shock the normally charismatic brother's
Mitsuya once came home to find them wearing his way too baggy for them toman uniform and pretending to be delinquent's.
Luna's favourite animal is rabbits where as Mana likes giraffes best
They both adore Taiju and think he's really funny (he spoils them a lot too)
In the future, Luna works in a high end office job, while Mana works with animals.
When they first saw Mitsuya's tattoo, they both loudly declared that they want one too
They also both wanted to learn to ride motorbikes (which they actually did later on)
