About the Killer-Turned-Trainer Thing

——When the world's number one killer picked up a versatile monster that could only act cute, his style of painting completely collapsed! Su Yangkong, codenamed "Kong", is the world's number one killer, ruthless and frightening. ——Until he was reborn in the world of Pokémon and found that he only had 90 days left to live, and his only partner was a... A loser who could only act coquettishly? ! "What I'm looking for is the Phoenix King, not a mascot!" ——However, this ever-changing monster seems to have no respect for his "killer temperament". His daily operations include: ✔Turns into an alarm clock to wake him up (and then gets slapped) ✔Stealing fruits from his tree (and pretending to be innocent) ✔Dance the seaweed dance in the community competition (forcing him to become the "gentleest trainer") What's even more outrageous is—— ✔System: Want to extend your life? Complete the task "Grooming the Variety Monster" first! ✔Former colleague: Sora, you are depraved. Are you actually making bento for Pokémon? ! ✔Phoenix: (Watching from the cloud) This trainer's... Style of painting is not quite right? As a result, the ruthless killer was forced to start a Buddhist pet-raising routine. But who can tell him—— Why is this good-for-nothing, ever-changing monster gradually changing his view of the world?
