ハッピーシュガーライフ [Happy Sugar Life]

A psychological horror manga from Square Enix, Happy Sugar Life follows a high school girl who will do anything to protect the innocent child she has taken into her care. Running for ten issues from 2015 to 2019, this series by creator Tomiyaki Kagisora twists the sweetness of its title into a dark exploration of obsession, abuse, and the lengths one will go for a twisted version of love. Its unflinching portrayal of toxic relationships and moral ambiguity made it a standout in the horror-romance genre.
