The tales of land was engulfed in a scary and not so horror war clash with over lord demon monsters like slime, spider, or dragon! Someday on Isekai world, 3 high school girls is being summoned by a dragon as a legendary heroes just like the story.

I love it, I'm finally on some manga anime RPG hero! 300 years has passed, and the warriors have levelling their power to max level, LV 100! But it is so weird, they didn't feel that much strong, and some slimes beat them easily. Feeling frustrated that they are still weak, and also because they can't find any cute boyfriend there, they want to escape from this fantasy simulator world and going back to their city! Join the battle with three 300 years old but cute waifu girls. Pick up your sword, blade, shield, bow, stick and wand to fight any slimes, spider, zombie, or a dragon with your over powered ultimate weapon and armor. Don't forget to max out your stats like attack, defense, and magic. You don't want to get hurt, right? But beware, because you cannot level up anymore. Also do not worry, when you are dead, you will get reincarnated again as a same hero. So what? It is wrong to not summon them? How? Try to get out from your old memories and have some adventure on isekai!
