Maybe it's the Discworld binge talking, but I think "Oni headology" would be more appropriate.

But yes, as neat as that cutscene was, I'm not exactly surprised. Suika's fairly smart, after all. That, and if you look at her IaMP story mode, you'll see that she's often in a lecturing mood. Almost more so than Shikieiki, actually. Certainly far, far more vicious about it in most cases.

Anyway, this sort of thing is why she's one of my favourite characters in the series

Also, next up, recruit Suika. Recruit her ten times, if possible. Those stats are just terrifying.
