Omg I really forget what the hell happened in this manga. I dont wanna reread this again man
Main character is a technically failure of a mage who had trouble learning the most basic spells, he and his familiar Poche (best character, technically main heroine) accidentally created and drunk/ate a potion that made them immortal. Several thousands of years pass as he's researching magic and they finally comes out of his home to explore. <-- Main plot.
They encounters a village attacked by monsters and rescues a trio of warrior siblings while helping the survivors. The youngest of the siblings, Rina (super cute, actual main heroine), accompanies them as his disciple and they head to the magic academy. Once there, they (and sorry the rest will be fast forward) meets Eileen the loli baba, introduced to a self-proclaimed genius, the hot mage girl Idea, and a muscled brain...muscle brain. MC becomes hated in the class (mainly those 3) but wanted by the big wigs (mostly loli baba), Rina and Poche becomes popular, MC becomes adventure meets a party of three consisting of Lead Smart Guy, Skinny Strong Guy and Betty the hottest character in the manga. Rina gets a dragon, MC helps Skinny Strong Gai free all the prostitutes from red light district introducing Haruhana (super cute but her booba tends to just vanish at times), tournament arc!, Rina kicks ass, finally showdown between Rina and MC, MC wins.
Bad stuff happens tons of monsters appears, MC endorsed by powerful people (mostly loli baba), his secret is discovered, plans fail, MC saves the day. MC leaves magic academy goes on journey. Umm.....stuff happens with a small chick named Melki? (my memory is hazy here). MC trains with magic master, gets jacked cause MUSCLE MAGIC! 2 year time skip aannnnnnd we've arrived.
Disclaimer:
It should be obvious that I missed a hell of a lot of details and skip over the names of those not important. Eh, the only ones I named were the girls? Nah, just your imagination.
