Action ~ op male leads

Absolutely love this!! The backgrounds of each of the characters are so emotionally complex and interesting. It’s not the typical “op mc” and the detective aspect of it is really nice. A man with multiple identities accidentally ends up becoming a professor at an esteemed magic academy and has to stay undercover to keep his identity secret. He ends up getting roped into a secret society that he must deceive, keep up with his appearances as a professor, and achieve his own goals at the same time.

Mc is given a chance to go back in time by his commander who has tried to save them from the celestial giants invading their world and sees him as their last chance with his resilience and ability to befall them. He goes on a journey to become even stronger and finds out more about exactly how the beings came there and why so many of the powerful people he meets on his second chance at life were nowhere to be seen during the battles.
