Lin Ye, a modern anime lover, traveled through time and became an ordinary human student in the ghoul world of Tokyo. At the beginning, he was caught in a fatal crisis of ghoul hunting. When he was about to die, he accidentally activated the Demon Slayer Summoning System, which could summon Demon Slayer characters, inherit the breathing method, and forge the Nichirin Sword to restrain ghouls.
From surviving as a weakling to summoning Nezuko and Zenitsu Zenitsu, to unlocking Tomioka Giyuu, Infernal Anjuro and even Stepkuni Enichi, Lin Ye relied on the power of demon slayer to rise strongly in the gap between ghouls and CCG. He dealt with the two major camps, got acquainted with Kaneki Ken and the people in the Anding District, reversed the tragedy of the original work, used the Demon Slayer Blade to tear apart the darkness, and protected the people of Tokyo. He finally broke the antagonistic fate between humans and ghouls and became the strongest guardian across the two worlds.
Very nice to look at.
