Spring Kagero

I've recently gotten 2 Spring Kegero's, so merged them and got them to level 40; but I've forgotten which IV's she has and can only figure out she has +Atk, but don't know what her Bane is; I think she gained +1 Hp and Atk when I merged her.

She is a +1 merged Spring Kagero
B - Bond Rank, S - Support Rank

Lethal Carrot+ (Spd)
Reposition
Luna

(A) Swift Sparrow 2
(B) Desperation 3
(C) Spd Smoke 3
(S) Guidance 2 (am on 98 Sacred Coins so will upgrade when I can)

Hp - 40
Atk - 51
Spd - 36
Def - 20
Res - 29

Can anyone help me figure out what her bane is?
