[Detective Conan] My Master and I Were Supposed to Be Earth's Guardians

Ah!!! Song Tiantian is adorable, but he's only the heroine's love interest! The master is the real male lead!! The real male lead in a familial-love story!! When she was five, Feng Jianming was on the verge of death. In a daze, she grasped the scarlet spear that appeared in her dream, and took hold of her own fate. A strange man with silver hair told her that this world was home to otherworldly creatures called "Zhang." If she found and destroyed enough of them, she could go with him to a wider world, where her illness could be cured. Feng Jianming readily agreed and became a Zhang hunter. Only... Feng Jianming: Master, how many Christmases have we had lately? Xie Wuyou: Three or four, I guess. Feng Jianming: You said before that we'd be able to go to headquarters after about another year... Xie Wuyou: Good apprentice, only half a year has passed in this world's timeline... Feng Jianming: But it feels like we've been at it for decades! Xie Wuyou: Ah, apprentice, that underground organization I've been milking has a bit of a situation. I'll go deal with it first! It really feels like I was conned back then. Scene One: Feng Jianming, who has congenital heart disease, keeps getting inexplicably dragged into all kinds of cases. When the vicious criminals are about to silence her, Feng Jianming steps forward and solves the source of the problem with one kick/punch. Everyone: Don't you have heart disease?! Feng Jianming: This is just a little perk that comes with saving the world. Everyone: Heh... Scene Two: Vodka: Boss, why do we have to buy so many phones every month? Gin: Obviously, so we don't leave any clues. The next day Xie Wuyou: Apprentice, take your time using them. I'll get you a new set next month! Theme: Nothing in this world is ever accidental.
