Shirohiyo - Reincarnated as a Neglected Noble: Raising My Baby Brother With Memories From My Past Life

At just five years old, noble-born Ageha Kikunoi has already been dealt a bad hand — overweight, ignored by his family, stuck in a remote corner of the Kiryuu Empire with zero allies. Then one day, memories from a past life as a Japanese man come flooding back, and suddenly he's got skills nobody in this world expects from a neglected kid: cooking, sewing, and a whole lot of practical know-how. Things get more complicated when his father introduces a new half-brother named Regulus, and Ageha learns this kid might eventually try to take everything from him. Instead of scheming or running, he just... decides to be a good big brother. He makes toys, cooks meals, and slowly starts turning their bleak situation into something warmer. The setting blends Western fantasy with Asian cultural elements, which gives the whole thing a distinct look and feel compared to your typical isekai. This is a 12-episode TV series from Studio Comet that leans hard into slice-of-life comfort. There's no power fantasy here — it's about a guy using mundane skills to build a family worth having. If you liked the parental warmth of If It's for My Daughter, I'd Even Defeat a Demon Lord, or the way Ascendance of a Bookworm turns everyday knowledge into something meaningful in a fantasy world, this hits a similar spot. It's quiet, wholesome, and genuinely cozy without being boring.
