Not that unfortunately ╥﹏╥
The only one story i know with sponsors is The Overpowered Newbie, but i dont think it fits what your looking for ┗( T﹏T )┛
maybe?? tbh it’s been yrs since ive read this manhwa/novel, but it feels roughly like this: https://www.mangago.me/read-manga/the_only_necromancer/
the clown reminds me of https://www.mangago.me/read-manga/leveling_with_the_gods/, but it’s definitely not what youre looking for.
there’s one more im thinking of but i don’t remember what it’s called/enough of it to try and search for it
MC is a guy, unkept black hair, eyebags, lanky. Genre is action, it's one of those game manifested into reality (?) or world suddenly becoming a game. There are sponsors if I remember correctly, there is this clown one that follows MC around. MC also gets a crow themed power up I believe. I also remember there being a girl next to him with long black hair and bangs (not a loli). MC definitely had a arc or a few chapters where he had to fight a boss in a circus/amusement park.
Think there was safe zones, but MC just went off and did his own thing.
I also believe that he had like this special access to the sponsors group chat where he remains anonymous and listens in on them, purple theme for this.
There was also a bit where they were fighting a dragon (like an eastern dragon, those longggg ones) in a skyscraper building and MC defeated it and broke through all the floors (I swear it's from this story)
Art style isn't like the conventional style, rough looking and stylised (best I can describe it)
Might've been axed but can't remember
Please help me!
