I've been trying to do Trinity C a bit underlevelled and undergeared. Been moving Tsubaki back and have uNeru ohko (needs Akane debuff and Kisaki buff) Koharu, then Azusa. After a few tries, I've learned that she can't deal with Hifumi so I put in dHina just for that. When it's just Hasumi and Tsurugi left, I run out of time before I kill both. Is there a specific order that I should be doing this in?
