comedyslice of life

Mahiro Oyama, a typical fan of erotic games, experiences a drastic change when he awakens one day in a female body. The culprit behind this transformation is none other than his mad-scientist younger sister, Mihari, who conducted an experiment that went awry. While Mahiro desperately seeks a way to revert to his former self and resume his reclusive gaming routine, Mihari is equally resolute in her scientific curiosity to observe this unexpected phenomenon. As their unconventional journey unfolds, one thing is certain – life is about to take a bizarre and unpredictable turn for both siblings.
