Zombie World de Harem wo Tsukurou!

Synopsis

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 shelter, they discover she's been bitten! Desperate not to die a virgin, Kana asks Koutarou to sleep with her before she changes, and he obliges, thinking this could be his only opportunity. After sharing their first time together, they discover a miracle: Kana's bite is fading away! Does Koutarou have the cure for the virus inside him? Convinced this is true, Kana is determined to stick close to him and have plenty of fun in the meantime. But when they make their way to Kana's school for shelter and protection, they come across something that could be more dangerous than the zombies. (Source: Seven Seas Entertainment)
