Zombie Sekai de Harem wo Tsukurou!

When a zombie apocalypse suddenly breaks out during the school festival, shogi player Koutarou manages to save the beautiful and buxom Kana just before she's taken by a swarm. But when they reach Kosaka Kotaro was living his best life as a gamer otaku... until the zombie apocalypse hit. Now the streets are crawling with the undead—and his biggest regret? Dying a virgin.

Then he rescues the gorgeous Kana, who’s just been bitten... and doesn't want to turn into a zombie before losing her virginity. Kotaro's happy to help—and after their steamy encounter, something incredible happens: her bite begins to fade.

Could the cure be inside Kotaro? Kana's not taking any chances. She's sticking close, keeping him busy—and making sure the "treatments" keep coming.
