Reborn a tale of a Mangaka with Cheats

Alex Walker is just your average Marbel American comic cartoonist when he suddenly died after saving a little girl from a truck accident. He Wakes up and finds himself as a useless hikikomori high school student in Japan Sapporo with a single mom and sister to take care of, pretty ordinary, right? haha!Outstanding haha! NOT! his father was a former washout legendary Mangaka Artist who quit the industry almost a decade ago but he just passed away leaving their family poorer than ever. Even his current mother had to work two jobs!

Alex decided to become a mangaka artist with the knowledge he has from his previous life to support his family and lift his family from obscurity and financial problems! but before he could do that, some shit happened, in this parallel world, none of his works or his predecessor's works exist in this world. In this world, Manga from his world doesn't exist. Reborn in a parallel world where famous works such as FragonbollZ and Card Camping Cactuar, Square box Spongeboxers, and Kyoto Ghouls DOESN"T EXIST! What would Alex do?

Alex would change the manga industry in this world and profit from it! by plagiarising! hahahaaha!
Famous works from anime?
Don't mind if I do!
Light Novel hits?
Don't mind If I do!
Expensive Merch like figurines? and plastic crap?
You know the drill!

Just so happens, he has a little system that gives me manga-related skills from his previous world. Noruto-style brush technique for the Mission reward? don't mind if I do!

hold up, something's not right.

Hey system, you're sealing all of my anime and manga skills behind a damn PAYWALL?! WHAT GIVES?! An Eldritch god is sponsoring me?! What the fuck is the dreamer?! Hey?! why is the world trying to stop me from changing stuff in this world?! The fucking Yakuza wants to kill me too?! Hey system, are you sabotaging me? you're doing this right? Right?!

Why is this system trying to sabotage my new Isekai life?! Screw it. I'll just do whatever I want.
