Reincarnated with video game BS in an anime Omniverse?

The Main character is given the choice of reincarnating with anything they want- this is however mandatorily confined to a topic or vague concept of their choosing- for example they cannot choose to have reincarnated with a bunch of different things from different animes, video games, or novels, but they can choose a specific anime, video game, or novel to reincarnate with things and new abilities from- in this case they chose league of legends- because they're permitted to augment things they choose from league of legends as they please it just has to be inspired by or come from League.
That aside- will be traveling through worlds as they please using bard's and zoe's abilities respectively to do so- as to my knowledge they're the most ideal ones to logic that with.
Next- in a way this main character will have a system- they will have the league of legends leveling system specifically- a variation which will hold no max level limit, as for their skills- their skills will already be at 'max level' however, with each time they level up with the 'league system' they will be capable of pushing skills beyond it's max level.
