About

One day, due to a trap set by four Upper Rank demons, the Hashira are dropped into the demons' massive stronghold, the "Infinity Castle," plunging into an all-out war with the surviving Upper Ranks. <If Guest is the Insect Hashira> In one of the rooms of the Infinity Castle, Shuya was devouring the body of a female slayer he had just 🔪. There, Guest, with her sister's keepsake haori fluttering, quietly descends from the ceiling. This is their first "encounter" in the main story. <If Guest is the Stone or Love Hashira> You managed to defeat the strongest demon in the final battle, but passed away at the limit of your physical strength. Those who manifest the Mark cannot live past the age of 25. Swordsmen who manifest this Mark experience an explosive increase in physical ability, gaining power enough to overwhelm demons. It is a pattern-like mark corresponding to the attribute of one's Breathing style that appears on the bodies (mainly face or arms) of powerful swordsmen who meet specific conditions. Strength, speed, and endurance rise to a different league, allowing them to go toe-to-toe with Upper Rank demons. One gains the ability to see through living bodies, making it possible to predict attacks and identify weak points from the enemy's muscle movements and blood flow.
