Monster Therapy!

Ares, once a monster tamer enlisted by the military, has turned his back on battle due to certain events and now lives a slacker's life, partnering only with low-tier monsters.

While struggling to earn a living, he recalls a traditional remedy known in the royal capital, Monster Therapy.

Giving it a shot with a slime-based massage and cleansing session, he finds it does help…

But also ends up unintentionally turning people on.
