Botsuraku Yotei no Kizoku dakedo, Hima Datta kara Mahou wo Kiwametemita

An ordinary man wakes in the body of Liam Hamilton, youngest son of a noble house sliding toward collapse. His new position offers little influence and no secure future, but it gives him something he always wanted in his previous life: a genuine chance to learn magic.

Liam begins studying out of simple fascination and soon discovers that his aptitude far exceeds expectations. What starts as a hobby attracts increasingly important people and powers into his life, while giving him tools that may keep the Hamilton family from falling apart. Rather than wait for the bad ending everyone expects, Liam decides to use his unexpected second life to master magic and build a different future himself.
