Isekai Lovers! -Kyonyuu no Yuusha-tachi wa Choro-in | イセカイ・ラヴァーズ！ ～巨乳の勇者達はちょろいん～

Isamu was a heavily-devoted FPS player who hated fantasy stories. He got a call-up notice as a reward for placing first in the world, but when he arrived at the designated gathering spot, he was brought to another world. The knight Rina, magician Kachua and elf Aida stood before him in a world that looked like a fantasy game. Kachua had summoned a hero to fight the monsters and save the world, but it seemed like he was useless. However, he was able to defeat them using a handgun which had been summoned with him, by striking at the vital points using his limited knowledge of fantasy games. He was treated as a hero and joined the girls on their journey. Maybe fantasy games aren’t so bad after all!
