Tsuihou sareru Tabi ni Skill wo Te ni Ireta Ore ga, 100 no Isekai de 2-shuume Musou

A mysterious god-like entity has given Ed a crazy ordeal in which he must be expelled from a party of 100 heroes in 100 different worlds in order to return to his original world, but he finally achieves the condition and is able to return to his original world. However, as a final additional condition, he is given the chance to "see what happens to the worlds he has been banished from."... This is where he learns a shocking fact.

"All right, I'll do it! I'll go there again and be banished for good all over again!"

Only this time he is accompanied to these 100 worlds by a former companion...

"Fufu~, don't worry! I'll be with you this time!"

"Yeah, I'm more worried..."
