A while back i was reading light novels, and ended up getting too busy and stopped reading them. I thought i had bookmarked all of them, but now I have noticed that i forgot to book mark one.
The light novel im looking for i have read some I just can't remember what its called. But I remember the MC was a male and that there are portals to other worlds. I believe that its a school setting as well. I also remember that when monsters are killed they have a chance to drop a monster card that can be bronze, silver, and such. I remember that one of the cards he got was from fish that ended up being a sword or something like that. I also remember that there is a girl that used to hate him, but then i think someone transmigrated into the mc's body and now hes different and she likes him. Her family still hates the mc but tolerate him for her.
I really want to read the book but i cant remember what its called. i also can't remember if it was on here or a different site XD. Help please!
