Kiriko is practicing summoning to fox spirit, but as she does, something unexpected happens.

The summoned fox spirit goes feral, and before she can figure out what's happening attacks Kiriko and dives straight into her. It combines with her spirit, possessing fucking with her head, changing her thinking and rationale.

In seconds, she turns from the confident and capable kunoichi to a much more... animalistic demeanor, sitting on all fours and behaving like a fox. Her true self back peak through every now and then... but no matter what, she's now a prisoner in her own mind.

Not long after, you find her.
