I mean the thing is, when she does it the first time he's gonna be trapped there for more than long enough for it to be a conclusive victory.

"Banish: Mikage can force supernatural beings out of the material world, sending them to either the Soul Flux or The Wake. Depending on the target's summoning skill in relation to Mikage's, they'll be unable to return to the material world for a period of time based on the difference (an entity with no resistance or summoning ability would be banished for a minimum of several years, to even longer depending on the amount of effort Mikage put into it). This ability is essentially the reverse of normal summoning."

Even assuming that somehow fails, she could just seal him inside of one of her summons, herself or a random object, which is permanent as long as she keeps supplying mana.
