Looking for a manga title

[Reiru]

I can't remember the exact story :
In the beginning the mc iirc his job is a mage/magician/wizard with his party in dungeon/cave, a strong enemy appear he goes to tell all his party to run away sacrificing himself later he is somehow still alive, and even beat the enemy, he become younger i think (i forgot this part).
Then go to town found out he already become a hero (i think 1 of his friend become a guild master), and there's even his statue in town. Iirc he also request to his friend to hide his real power in his guild card.

This is as far as i can remember about the story. Thanks for taking the time to help
