Just imagine, Kokona when she's as old as Shun. Would she get bigger than her sister?

Shun is probably the best student you can get from the initial roll because she's the only one you can't farm in any way and you're at the mercy of gacha to get her. Hina's free after 2 weeks of playing and has 2 farmable nodes. If I were you, I'd go for Shun + Aru or Hibiki because Aru and Hibiki are really painful to farm (max 3 (6 during 2x weeks) shards (used to unlock students if you don't have and to upgrade if you do).
t. someone who spend 5 painful months farming Hibiki
Warning - Hibiki's going to turn you into Ryan Gosling, at least mentally.
