Through that spell, my lowly self has sworn complete loyalty to the brilliant Iizunamaru-sama.

I am too afraid of the consequences to ever, ever betray her trust—

Y-Yes! That she does, that she does.

That's an expertly crafted Izuna spell.

Buddhist magic or not, it's a very powerful command charm.
