Crossover Anime: After marrying into Yukino's family, I joined the group chat!

Travel to a crossover anime world where god-slayers and deities coexist, and cursed spirits and demons dance together.
Lin Qingping, a test-taker from a small town, successfully entered Soubu High School with the highest score in the Chiba City Unified Examination through his own efforts. He was then chosen by Mrs. Yukinoshita to marry into the Yukinoshita family!
He became Haruno's fiancé!
I thought I could only live off women for the rest of my life, but unexpectedly, I awakened and upgraded my panel!
Copy the Mystic Eyes of Death Perception at the start, and reach max level with one click!
I'll kill even gods if they're alive!
Yukinoshita: "Yukino is one thing, but why did you even... Mom..."
Yukino Yukinoshita: "I'll say it again, don't call me 'sister-in-law'! I was here first!"
Suoh Yuki: "My brother is mine!"
Hinata Hyuga: "Luckily, I only have one younger sister."
Kaguya Otsutsuki: "Hagoromo Hamura, why aren't you coming over to pay your respects to your Uncle Seihei?"
Lin Qingping: "At first, I really just wanted to be a kept man!"
