did i fuck up?

i've been sitting on a choice between shiro terror, m.arisu, and wakamo for a couple weeks now.

i finally jumped the gun and put wakamo at 5star/ue30. i've got 1600 ligma left it's enough to ue40 wakamo and ue30 m.arisu or shiro terror since i got a dupe of both of them. that or keep wakamo at ue30 and ue40 m.arisu or shiro terror. my thought process is wakamo can be an assist, but i've got c.hare, d.aru, and seia to act as hypercarry buffers so maybe it's useless? wakamo was useful on my chokmah.

i got ue50 s.hanako and ue50 s.neru as my main carries atm and need to try to fill out blue.

i can nearly 5/10/10/10 shiro terro or m.arisu. that or just forget blues and put the ligma into mika(i see she's 4/5 even on blue raids). i've got the tanks, healers, and buffers sorted out

where can i see a list of upcoming events/raids? i also mean the i think "mini-events"? like we had last week with sephira/valentine's day. i'm trying to plot out how i should spend resources.

a list of raids in order would be great too cause i'm not sure what anniversary i should spend my ligma on and the only content i've got left is the raids.
