Tensei shitara Dainana Ouji Datta node, Kimama ni Majutsu wo Kiwamemasu

In his previous life, he loved magic more than anything but lacked the talent and noble blood needed to master it. After death, he is reborn as Lloyd, seventh prince of the Kingdom of Saloum, with an enormous supply of mana and all the time he could want to study what was once beyond his reach.

Far from the line of succession, Lloyd uses his freedom for experiments, forbidden books, and increasingly dangerous spells, rarely caring whether his achievements look impossible to everyone else. His curiosity leads him toward sealed demons, ancient secrets, and enemies who fail to realize how deeply the quiet child understands magic. Saving the kingdom may matter, but to Lloyd, every crisis is also an excellent opportunity to test a new spell.
