This is marcus I am not ending the book with these I just wanted to put them inYeah I know he looks like a girl that's because I suck at drawing guys eyes

Marcus tartaros is mard geer's son

Yes he was in the guild tartaros but he never saw anae because his father hated humans and thought one being near his son was horrible soon once he got into his teenage years mard geer let him interact with others

He trained anae for some time in demon slayer magic and anae showed him god slayer magic

Once anae left she forgot all about marcus and he didn't forget

He soon went into the normal word and then joined fairy tail
