    All of these are Demon Slayer series with two male protagonists. The first one features a protagonist who joins Muzan's faction; the protagonist is an original character who eats people, and the relationship between the protagonist and Muzan is very sweet. The second one features Kokushibo as the protagonist's partner; he's human in the beginning but becomes a demon later. The third one has two couples. The fourth one features an original protagonist with a universally adored personality; I still ship Doma the most, hahaha.

    A truly outrageous turn of events has arrived in Demon Slayer fanfiction! The youngest son of the Tsuigoku clan, who seemingly appeared out of nowhere, has actually transformed himself into a demon, becoming a demon king immune to the sun?! Kokushibo is questioning his existence, Yoriichi is forced to have his worldview shattered, Muzan is furious, and even Ubuyashiki has to keep stomach medicine on hand—this generation of Tsuigoku's kids is just too much trouble! The protagonist is both tsundere and cunning, and his interactions with his Upper Moon brother and the initial swordsman brother are consistently high-energy, with sweet moments hiding hidden daggers, but the sweetness outweighs the daggers. There's no romantic pairing yet, focusing purely on family bonds. Demon Slayer fans, this is a must-watch!

Muzan Kibutsuji: “I could run away when facing Yoriichi, but against Si Shu, I have no choice but to die!” Yoriichi Tsugikuni: “Your strength has surpassed mine!” Demon Slayer Corps: “Lord Si Shu is the most powerful man of all!” 4.3kReads9.1Score53614d adds

    Muzan cried out, "I could still run from Yoriichi, but against this guy, I'm doomed!" Even Yoriichi exclaimed, "You're even stronger than me!" The entire Demon Slayer Corps turned into fanboys, shouting, "Liberator is awesome!" He was supposed to learn how to use Moon Breathing to be a villain, but he turned it into a skill exclusively for slaying demons. This reverse mentoring was hilarious! The satisfaction of watching him pin Muzan to the ground and beat him was more addictive than eating ten pounds of Mitsuri's rice balls!
