I'm Really Not a Demon Beast

Summary

Li Lin, a “homebody,” is transported to an alternate world inhabited solely by women, where he unexpectedly awakens a weapon system—whenever he sees an enemy, the “emotions” he feels can materialize into “weapons.” As the only man in this world, he is rejected by the world’s will and branded with an “expulsion curse”: his body will gradually shrink until he vanishes completely. To remove the curse, Li Lin embarks on a journey into the unknown.
