Not so interesting but not exactly bad. A normal guy with 1 sister and mother suddenly gains a unique ability which is regarded highly as smth rare in that world. Even so, he's stuck at level 1 meanwhile his egoes a heavenly/holy sword(elle) and a demonic sword(lou) and some other egoes he bought in a certain store have drastically leveled up. In his journey to bring an elixir for his mother, he gets attcked cuz he was misunderstood as a spy. He escapes and survived with the help of a girl/woman that is multiple times stronger than him. She helps him in exchange for him to be her disciple and they promised to meet again in level 50. Recently, he managed to make another gate his ego..this gate is different than the others tho. It has a mind of its own(?) It's a lich. Instead of that, he also has a prospective father(not yet just has a crush on his mom) that helps him all the time from job to taking care of his mom and providing many help from the association to him. It turns out he was the son/grandson of the president
