Shirobuta Kizoku desu ga Zense no Kioku ga Haeta node Hiyoko na Otouto Sodatemasu

After regaining memories from a past life, a neglected young noble begins looking at his world very differently. What matters most to him is no longer status, but the chance to care for his baby brother, whose presence brings warmth to a household shadowed by aristocratic tension, magic, and the influence of higher powers.

Blending reincarnation fantasy with family-focused slice-of-life storytelling, the series follows an older brother who uses ordinary skills from his past life in unexpectedly useful ways. Small acts of care, domestic ingenuity, and a growing sense of responsibility shape the story as much as its noble setting, giving it a gentle tone with light comedy and heartfelt sibling charm.
