I mean if you really consider it Yuuka does also look after Aris like a big sister would and seeing all the cr-p the poor girl was put through BECAUSE of Rio & Himari I honestly think she deserves "SOMETHING" for all that mental pain and suffering, else we end up with that alternate time line version of Aris we're she kills everyone.. a HAPPY Aris is a Happy Kavots after all.
I feel bad for Alice because she risked her life to work hard just for that gaming console. Rio reminds me of Stepmother from the Disney Villains while Himari was Alice's fairy godmother. But in the end, Alice finally got the console by the help of her third mom Yuuka. Well done, Yuuka you may be a nice person sometimes.
I mean yuuka is a mommy for gamedev club specially alice, in last volume she is worried because alice got on the spaceship, it reminds fanart of them when alice as baby holding a game console while yuuka want give alice a calculator
