Isekaigaeri no Ossan wa Fusei Skill de Fathercon Musume-tachi wo Torotoro ni

At fifteen, Nakamoto was mysteriously transported to a fantasy realm where he spent years growing into his role as a hero. Now back in modern Japan, he faces an unexpected challenge: reintegrating into a society that sees him only as a middle school dropout with an inexplicable gap in his history. While struggling to build a normal life through part-time work, his mundane routine takes a fantastical turn when a mysterious girl named Angelica appears, claiming to be from the same world he left behind. As more figures from his otherworldly past emerge—including someone who bears an uncanny resemblance to a person he once cherished—Nakamoto finds his ordinary existence becoming increasingly extraordinary. With abilities he gained from his time away and new relationships forming around him, he must navigate the delicate balance between the life he left behind and the one he's trying to build.
