Summon the 2D Battle Girl

Some people are carrying big swords and slashing in all directions, some are dancing with flying swords and spinning in the air, and some are making fireballs to control the whole place. But the most outrageous ones are those summoners. They don't summon monsters, but mountains, seas, and atomic bombs! Lao Chen said that as a summoner, he was very panicked now because the person he summoned might punch him flat at any time. This novel and its characters are purely fictitious.
