If we are talking meta after this banner we have C Hare and Himari which are very good supports, then Fuuka which is limited and Akari that it's also good.

Dress Aru also is good and the twins which are also limited and very decent.

In the waifu aspect, just see if any girl interests you.

Honestly I would recommend spending 2 sparks if you are new. I think the most important unit to get when you are new is Summer Hoshino.
