In the vast majority of the Banishment stories the Hero is so full of himself that he thinks that all he has to do is kick out the one other guy in the party so "I can have all the bitches!" and that he's strong enough it won't matter. His skull is empty and he thinks with his pecker.it is the usual but is the hero stupid? unlike other series where the MC mostly do "invisible buff" but in this one, everyone else clearly know about the effect his skill has on the party, even worst is trying to challenge A-rank dungeon without even try to find a replacement healer.
Occasionally you get one that is a little different, like S-Kyuu Boukensha ga Ayumu Michi: Tsuihou Sareta Shounen wa Shin no Nouryoku 'Buki Master' de Sekai Saikyou ni Itaru / The Path of an S-Class Adventurer: The Exiled Boy Becomes the World's Strongest With His True Ability, "Weapon Master". As is obvious from title this is based on a WN or LN.
