A patched-up fence constructed of scraps of wood and metal, featuring spikes and the corpses of executed sorcerers that dominate the overall look of the Square the fence encircles. The field is irregular and has chasms of water all over it, making it difficult to play baseball or other do other activities if one is not cautious.
When the Militia was wiped out by Shin, the Torture Square was converted into a baseball field, but the old corpses of Magic Users still hang as a reminder of the past.
The match between Dr. Vaux' "Worms", composed of a motley crew of his friends, monsters, zombies and our protagonist, was held against the "Sharks" of the Hole's clinic. As its director and Vaux hate each other, this rivalry is disputed once a year in a baseball match, but unfortunately they are never able to settle a proper score thanks to Kaiman's ruthless way of playing, that usually tends to leave someone unconscious and the match suspended for a year.
Fujita and Ebisu went to Hole to take revenge on Kaiman and Nikaido for killing Matsumura, and ended up enrolling in the Shark's team. So Fujita would have the opportunity to face Kaiman and kill him for good he became the team's pitcher, while Ebisu was made the team mascot. To Fujita's horror, Prof. Kasukabe had Matsumura's body stitched back together and turned into a zombie to have someone play on the 3rd base. He quickly changed his initial plan of going against Kaiman and escaped with Ebisu and the remnants of his dead best friend to the Magic User world. As Nikaido broke the clinic director's jaw due to the strength of her throw, the match was once again suspended.
