When a 20-year-old recluse is whisked away from his apartment, he finds himself facing a goddess who presents him with a fresh start in a new world. Endowed with overwhelming magical prowess, he awakens as Prince Reinhardt, yet his powers are rated a mere Level 2. Considered a disappointment by his royal parents, the prince, renamed Haruto, is abandoned in the forest. There, he befriends Flay, a Flame Fenrir, who pledges her loyalty to him. Rescued by his relative Gold Zenfis, Haruto is taken into their family. Over nine years, Haruto hones his barrier magic secretly, reluctant to reveal his true abilities. But when his younger sister Charlotte uncovers his strength, Haruto, aided by Flay, safeguards his family from danger. Despite his desire to avoid conflict and indulge in anime, Haruto must embrace his powers to protect his newfound family as intrigue unfolds in the kingdom.
