Dio Calmis

About
Dio Calmis was a Tousho that was sleeping in the floating land of Ylapu, which in reality is the Toushin Toshi linked to Upsilon. Among the created Tousho, he claimed to be the strongest of all and was sealed due to being too dangerous and violent. Prior to his transformation, Dio was a famous assassin with obscene fighting skills, to the point his name shaked the world, even when he was still human. Dio is a sadistic and cruel individual that takes great pleasure from killing.

He was a strange case because Dio didn't believe in Magic, despite living in era dominated by magic. He was called the ultimate assassin of mages due to the immunity he developed towards it thanks to his lack of belief over it, and was put to sleep by Freak Paraffin because he was deemed as too dangerous. It is unknown how someone like him came to become a Tousho.

During the events of Rance IV, he was reawakened by the leader of a Helman Platoon that was exploring Ylapu in search of a Toushin and was forced to work for them after bombs were hidden in his body prior to being awakened.

Abilities
Dio claimed to be the strongest Tousho and he wasn't bragging. His strength in physical combat was terrific, even for Tousho's standards. Rance's party fought him and was forced to retire several time to the point they didn't want to consider fighting him again. While his strength was truly remarkable, it is unknown if he truly was the strongest Tousho, since Tousho Bastet was also claimed to be the mightiest.

He could also defeat with ease Replica Misly, another Tousho and with a level skill for fighting. Hubert and Freak were also unable to defeat Dio. The only that could take on him was Hunty Kalar, who by herself is one of the world's strongest mages and one of the most powerful characters in the setting and even then she needed to make use of Shiranui in order to win, which says a lot about Dio.

He has a Lv2 skill in Kenpo and a Lv1 in Sword Combat and Guard. His level and cap are unknown but are presumed high.

Dio's most unique and impressive talent is his high magical endurance, Tousho are usually known for being weak against magic due to their low magic resistance, but that isn't a problem for Dio. Magic damage can be reduced with a strong enough mental fortitude and, for some reason, Dio doesn't believe in the phenomenon to be "magic", which allowed him to develop an immunity towards magic itself.

He was the ultimate assassin of mages whose strength in combat seemed to lack weaknesses, and given his personality, it's no surprise he was put to sleep for being too dangerous.

Rance IV
In Rance IV a Helman Squad led by Bitch found his sleeping body and re-awakened by Shizuka Masou, although not before hiding several bombs within his body. With the threat of an instant-death with the explosives, Bitch convinced Dio to follow him.



He chased after Rance's party a few times in the Toushin Toshi but they managed to escape every time.

He later encounter Replica Misly and engaged in a brief fight against the Tousho, which Dio won with ease due to the big difference in strength.

Eventually, after Bitch was killed by Toushin Upsilon, he murdered Dens Blau and fought against Hubert and Freak Paraffin. They were unable to defeat Dio and he was about to kill them until Hunty Kalar showed up. Dio underestimated Hunty, laughing at the thought of a Kalar being their "savior", oblivious to Hunty's true strength. He was defeated by Hunty and presumed dead at the fall of the Toushin Toshi.

Quotes

Trivia

 * Coincidentally, Dio was born in the year GI0420, the exact same year in which the Dark Lord War broke out.
 * The fact that he doesn't believe in Magic is rather strange, considering that he lived in the era of the Holy Magic Sect and was made a Tousho thanks to the Biometal magic created by M.M Rune. It is possible that he simply sees the art as a branch of science.
