I am in agreement with Tenhou, Avengers are too risky and Roanna seems especially suicidal with her SAW. I suppose this is a unit where it looks good on paper but in practice it falls apart.

For those wondering for Bonbori, she is used only for the event unit who matches Bonbori's current skill. As such Bonbori can have multiple skills though that depends on the event unit being sponsored. Bonbori can be used for non-event units as well but only if they share the same skill which is rare. I want her mostly because she is super cute.

Is there really a 100% drop rate for the first run of any map? Thank the Gods if so! And Aigis as well!
