Demon Slayer: Neighbor Butterfly's House Becomes Stronger When Being Chased

Travel➕System➕Two self-created breathing methods Traveling through the world of demon slayers, I actually became the neighbor of the Butterfly Sisters! When she encountered a ghost at the age of 10, Maple Moon accidentally awakened the "Pursued System" - she could become stronger as long as she was hunted. After that, the ghost camp exploded! Tong Mo: "You were so weak just now, and you suddenly became stronger. You must have been pretending before!" Wuxian: "I really don't understand why these losers are being killed one after another!?" Hei Shimo: "In hundreds of years, you are the first swordsman worthy of my full strength!" However, the Demon Slayer Squad... Iron Tomb Firefly: "Maple Moon! You actually broke my Nichirin Blade again. Pay with your blood!" Black Feather Maple Moon: "I was wrong, let's continue next time! Mr. Steel, your pursuit effect is really surprisingly good!" Kanae: "Ah, Maple Moon-kun, I'll leave it to you, little Shinobu." [Single heroine: Butterfly Ninja]
