Part-Time SWAT

A somewhat decadent sophomore student accidentally received the guidance of a famous teacher, embarked on a journey to cultivate immortality, and became involved in the dispute between the immortal world and the demon clan. Adhering to the principle of keeping a low profile, he pretends to be a pig and eats the tiger on campus. The heroines with different personalities will not let the protagonist go, and they will have to play the protagonist to death. What kind of world is this? Cats are working as groomsmen for mice, and they still don't want to let people live.
