Demon Slayer: Extremely Breathtaking, I Was Frightened and Stunned with One Knife

[Demon Slayer Fan + Invincible + Easy + Passionate + Not the Holy Mother + Daily Interaction] Traveling through the world of demon slayers, Kamiki Taki is bound to the "god-level salted fish system". As long as he remains lazy and lethargic, he can become infinitely stronger by signing in every day! As a result, the Demon Slayer Corps has a "sick" swordsman who can fall asleep anytime and anywhere and can barely hold a sword. Tanjiro: "Although Kamiki-senpai is very sleepy, he is really a gentle and good person!" Butterfly Ninja: "Every time this guy eats and drinks in Butterfly House and still sleeps soundly, it makes me so angry!" Until one day, the ghost of the second string attacked, and everyone was in despair—— The sleepy-eyed Kamiki Taki stretched out, picked up a branch, and split the sky with the never-before-seen "Ultimate Breath"! Onimbutsuji Muzan was horrified: "This sword... Is even more terrifying than that man named Enichi Tsukuni back then!!!" Zhongzhu: "..." Do you have any misunderstanding about "sick and weak" or do you have any misunderstanding about "powerless"? Only then did everyone realize that the sickly salted fish they thought they had to protect at all times seemed to be the most terrifying existence in the world!
