Inukami!

Keita enrages Yoko for trying to pick up girls while out "patrolling," so she teleports him naked into the middle of the city where he's promptly arrested.  Spiritual Investigator Karina offers to wipe his criminal record in exchange for exterminating a certain evil spirit.

When a memorial is destroyed by a member of the local university's karate club, their entire team gets possessed by dog spirits! Keita and Yoko are hired to exorcise the spirits so they can rest in peace.

Kaoru asks his ten Inukami to exterminate a suspicious spirit that has been appearing at the Water Garden's swimming pool. They're less than amused when Yoko shows up as well, but there's little time for fighting as the spirit shows itself.

Nadeshiko arrives at the Kawahira household to help take care of Keita temporarily. The rest of Kaoru's Inukami are overjoyed, but Yoko couldn't be more irritated by her presence.

As Nadeshiko departs, she wonders why Yoko chose Keita. It's time to take a look back at when Keita and Yoko first met, and what happened when they formed their contract.

An escaped demon uses its powers and leaves Keita and Tomohane stuck together. They need to hunt it down if they ever want to be separated again.
