Oni Gyaru-san! Kikisemaru!!

Several months have passed since a mysterious gateway to the underworld opened, initiating an unprecedented era of cross-cultural exchange between humanity and its otherworldly inhabitants. As society slowly adapts to this extraordinary new reality, ordinary high school student Tsuna Sakurai finds his daily life turned upside down by an unexpected development. Under the terms of this interdimensional integration program, he is suddenly assigned a supernatural housemate: a young oni girl who is scheduled to move directly into his home. Far from the fearsome demon of traditional folklore, his new companion proves to be a vibrant and endlessly energetic gal with a bold personality. Her excitable nature and spirited demeanor immediately clash with Tsuna’s quiet, unremarkable routine, throwing his once-peaceful existence into delightful chaos. As the two navigate the challenges of living together under one roof, they must bridge the vast cultural gap between the human world and the underworld. Their unlikely cohabitation becomes a microcosm of the broader societal shift, promising a lively story filled with comedic misunderstandings, heartwarming moments, and the unique struggles of sharing a home with a delightfully overwhelming demonic roommate.
