I've been looking for a manga I read but can't remember it's name. From what I remember, the main character and his party were fighting a demon army in a rift and seeing how it was an unending fight he tells his two party members to leave the rift and he'll stay behind to hold them off for as long as he could. He ends up defeat them all and returns years later only to find that he hasn't aged and the world thinks he's dead.

I think his name was Lock or luck, his two party members were prince now king and the other ended up as the guild master of the adventures guild.

Reality is a momentary dream but a dream is a reality for an eternity.

Koko wa Ore ni Makasete Saki ni Ike to Itte kara 10-nen ga Tattara Densetsu ni Natte Ita.

Thats it. Thank you.
