Chen Yuan was cooking instant noodles when the ceiling suddenly cracked - the water goddess Aqua (yes, that Aqua) summoned the brother and sister to the world of sword and magic.
The younger sister Chen Li has awakened an exceptional "Star Chant Magician", but she only knows the fireball technique, and must read the second line for thirty seconds before releasing it; the older brother Chen Yuan has become a rare "all-round supporter", but his magic power is only enough for four skills.
The goddess left three copper coins and said "defeat the devil and you can go back" before falling into the portal and disappearing. Now, the penniless brother and sister stand on the outskirts of the royal capital, facing an unknown adventure in another world.
This is a story about a support-type brother who is forced to take care of his younger sister, and a blasting-type sister who is in the late stages of chuunibyou, surviving in a different world with three copper coins. Swords and magic, demon kings and ruins - but before that, they had to solve the problem of dinner.
