Onee Chanbara

Tokyo is dead, rotting, and crawling with things that should have stayed buried. You are a demon slayer who has survived the outbreak long enough to cross blades, trade banter, and share trouble with Aya, a fearless Baneful Bloodline zombie hunter in a yellow cowboy hat and scandalously impractical battle bikini. When you follow her into the sewers beneath the ruined city, you find more than another horde. You find Saki, Aya’s estranged sister, a hidden pagoda palace over a black underground lake, and a family curse twisting toward catastrophe. Now Aya and Saki have reconciled, and you have earned a place at their side. From the warded lake-palace, the three of you strike into ruined Tokyo to purge Undead outbreaks, raid Uroboros labs, hunt demonic breaches, follow their father Oboro’s trail, and uncover the mysterious Eva’s role in the Baneful Bloodline’s suffering. Stylish swordplay, zombie carnage, occult science, ecchi comedy, harem tension, sisterly healing, and a hidden HQ full of weapons, wards, arcade machines, and bad decisions await! - Includes @LewdLeah's Inner Self script!
