[...ah. And there's the thing he has been avoiding all night.

He does know that it's probably going to be necessary, especially if they're going to win this grail war. He just plain uses too much of her mana to not need one, which is another reason he would have preferred to have been summoned as a Caster instead of a Berserker. But it is what it is, and he's not unfamiliar with the concept of 'mana transfer'. Familiarity doesn't make it any easier, though.]

...er.

[He's actually sitting up now, and he's turning...bashful? It's a strange look on the guy who has been permanently cheerful (or raging) this entire grail war. But he is young, even if he is a heroic spirit. His apparent age might betray just how little experience he has in these matters.]

I'll still go into spirit form, b-but don't feel like you have to do a mana transfer later. Not if you don't want to. I'd rather it be...mmm.

[And because he is a little shit, he goes into spirit form right then instead of explaining himself. Have fun stewing on those words while you rest.]
