Things are moving far too quickly for Ib to do much more than try her best to keep up. Losing her sword is no big deal, she barely uses it anyway. But Luffy actually wants her to hit him with lightning again?

She isn't sure what Luffy or MarKus is planning, and there's no time to waste protesting or asking questions. So she casts her spell again. First on Luffy's foot, then on her own sword. Lightning crackles through the air, charging the atmosphere so much that she almost doesn't notice when the protection spells wash over the party.
