[Yan Yuan] Where Can Kindred Hearts Find Hate? 【严缘】同心何处恨
A Demon Slayer fanfiction: Kokushibo (Michikatsu Tsugikuni) x Yoriichi Tsugikuni The characters' relationship has significance. Please don't make personal attacks. A collection of ideas about the brothers, where inspiration will be added from time to time. The characters belong to the original work. There are some original interpretations, and this isn't meant to be strictly canon-compliant. Treat much of it as an alternate universe. If that's not for you, please leave.

- 66 Upper Moon One Is Getting Stronger Today, Too 上弦一今天也在变强 Content warnings: This story leans toward a dark take on Nichirin. There are no romantic pairings, only platonic relationships and guidance. The author recommends it this month. Read with caution if that’s not your thing. The protagonist really does kill and eat people. He will not be redeemed. Although he transmigrates, this is not a body-swap or an assumed identity. He is simply one person. There is a courtesan storyline. From the day he transmigrated as Tsugikuni Iwakatsu, Yansheng knew 1.7kReads8.2Score23014d adds
