anime system reincarnator(dropped)

An otaku died getting struck by lighting and so he went onto another world with a few gifts in which he already knows the future/plot of the story so he wants to have some fun and change what he disliked. watch as the main character gets immersed within this world and starts to love it as if his own and the twist his he might not get to stay so long. Disclaimer : anything within these anime do not belong to be in anyway or fashion and if i may get something wrong then stick with me please as im just getting started.
