One correction, History's Strongest Senior Brother isn't actually Second chance(whomever labelled it that is an idiot who never read the book properly) as the MC got isekai'd, was abruptly killed in the great cataclysm and reincarnated into a lower/minor world within the same realm many years later(apparently the original world got broken up into many fragments or something like that). It would be more accurate to list it as Reincarnation(if you are willing to add reincarnation to the list XD).

To confirm, the MC died once, got isekai'd. Died abruptly due to a great cataclysm which broke the world, and got reincarnated in a different body WITHIN the same realm, just within one of the lower worlds that is a fragment of the broken world many years after the great cataclysm occured. That is what I understand from the story, but I can assure you that it is NOT second chance, and the tag is a mislabel.

Thanks for the list.

Would love some more detailed descriptions, but this is still helpful.

Some suggestions: 

#13 Possessing Nothing "second chance "

should be a combo since it's both second chance and isekai.

#18 The World of Otome Games is Tough For Mobs

could be updated from "isekai'd" to "isekai'd into game"
