Honestly? I see it!

Magia Record stuff btw- I know nobody understands it besides one of my friends irl but whatever,

Rena is a sort of tsundere, but not really. She hates being proven wrong, and hates showing that she loves a person, mainly platonically. She likes to one-up people, and doesn't want to be seen as weak.

Kaede is much more different, she's emotional and quite honestly adorable. She's open about being weak, and enjoys being in groups. She's shy, but if she lies something she's not afraid to show it.

Kaede and Rena in Magia Record both like playing arcade games, and are really nice friends.

I think they'd work really well together! :)
