Munou Atsukai sarete Party kara Tsuihou sareta—kedo, Nazeka Onna Yuusha ga "Kimi ga Hitsuyou da" to Itte Issho ni Tsuitekita!?

"Let me be clear here! We don't need a luggage carrier ranger who can't contribute to the fight at all... If anything, you're just luggage yourself, so please leave. And of course, leave all your equipment and money behind!"

Rielle, a ranger and the founding member of the party was asked to leave by his friends with no prior notice of his removal. When he became an adventurer, Rielle's first skill was the worst of even the shitty skills: Playing Dead. Rielle himself was fully aware that he had been left behind by everyone's strength, so he worked hard to make them proud and learned countless non-combat skills like lock picking, locating traps, studying about the monsters, and equipment repair and maintenance. In spite of this, he was ruthlessly sentenced deep in the labyrinth, and if he was left behind out here only certain death remained for him.

The Hero was furious. "You selfish bastards! Then I'll go with Rielle! I'm leaving you guys here!"

"Wha... What are you saying? What would this party be without you? We need people stronger and more capable than him. Okay! I'll put Rielle's banishment on hold!"

"It's too late now! I can't be with you guys who can't even take good care of your friends anymore!"

Rielle went out of the labyrinth with the Hero Lunas. Rielle vowed to follow her for the rest of his life. At that moment the hero began to speak. "I have a reason to not let you go." The reason why it has to be Rielle had been revealed, his secret and the true power of the the shitty skill "Playing Dead."

The Hero Lunas told Rielle that if he's with her, they can go anywhere and so, Rielle turned over a new leaf and went to adventure. This is the story of the most irreplaceable person who supported the hero to eventually bring peace to the world.
