Medina

Medina (메디나) is a parasitic organism that resides in the brain of its host. It is considered a Regular and is fully capable of sentient thought. It tends to dominate and control those it infests, although a strong enough will can apparently resist its influence.

The Medina was chosen as a starter in the Workshop Battle's Developing Tournament by Devil Bon. It entered the Tournament inside another Regular, whom it coerced into getting defeated by Boondawan. After the Regular was killed and dropped in the river, the Medina escaped and returned to Devil Bon, who planted it inside Beta so that he could participate in the Tournament.

During the Workshop Battle's Semi-Finals Beta intended to kill Viole's teammates while holding the Medina, however during the Item Shop Laure immediately detects the presence of the parasite inside Beta and thus induces vertigo so that Beta vomits the parasite out of his body. Beta tries to recover the Medina but it was ultimately incinerated by Yeon Yihwa's flames.
