He participated in every war he could, and when there wasn't one he worked as a bodyguard for the merchants, usually targets of local bandits. Because he took his enemies' weapons, he developed a form to wield any weapon with ease. He called this style "Riese Apostel" (Giant Apostle in German, translated as Largus Apostolus in Girardot's profile, which has the same style) in honor of the nickname he got in the battlefield, Riese.

During his travel, Johan met with the Azure Knight Nightmare. Nightmare killed the entire unit, including Johan's sons, but left him alive and scarred.

Johan returned, bearing a frightful scar on his armor. He revealed the information about Soul Edge, its existence and the events surrounding an Spanish port town and Captain Cervantes.

Although a benelovent man, he fell into the influence of evil and sought the mystical sword Mekki-Maru to grow in strength. Hachibei, formerly co-leader of the group, escaped with the blade and his daughter, Chie, into hiding. Still, Toki would not stop until Mekki-Maru was in his possession, so he sent various ninjas, Taki with them, to find him. Eventually he found out Taki lied to him about Hachibei's death in an attempt to cover him, and he sent his right-hand man Geki to retrieve Mekki-Maru from her. Geki isn't successful, but Toki kept sending ninjas against his former student. His last battle was against Taki in the Buddha Sanctum.

A prolific Italian merchant and Voldo's master, Vercci amassed fortunes dealing with the Spanish Armada, which he supplied with weapons. Thanks to the supplies he delivered (weapons mostly) he was known as the "Merchant of Death". He always was proud of saying he had everything he wanted. here was one thing Vercci didn't have: Soul Edge. He decided he would find it and, once his opposing brothers were out of the way, he gave Voldo the work of leading the search. He contracted mercenaries and pirates to search land and seas, but to no avail. He even contracted Cervantes de Leon's aid, which he accepted since he was one of his clients when he turned pirate. Finally he decided to lead the search. During his travels along the world he gathered many treasures, but wasn't able to find the swords. Worse yet, he received notices about the breaking of the Italian Wars and that his house, along with his possessions there, were lost. With only the possessions he carried with him in his search, Vercci went into an unnamed island on the Mediterranean and commissioned the digging of a 50 meter deep shaft. This pit would serve as a safe for his possessions, as well as his tomb. Once it was completed, he ordered Voldo to slay the sailors that had aided Vercci in his search, so they could not reveal the pit's location. Vercci died before knowing of the Italian Wars' end, but he still communicates with Voldo, still ordering him to search that last treasure he never got: Soul Edge, though it is possible that this is just Soul Edge itself tricking Voldo into following its commands.

She was the daughter of Kong Xiquiang and Chai Xiangfei, but because their love was forbidden, her mother was dismissed of the temple and she taken as an "orphan". After finding out her father stole the sacred Krita-Yuga, she thought she wasn't worth of the sacred sword, he monks reassured her that she had surpassed his family's stain and is more than worthy of wielding the sacred mirror, Dvapara-Yuga. Unfortunately, the night of the ceremony the Evil Seed rained down into the temple, turning the monks into berserk killers. Dvapara-Yuga protected her from the evil influence, but seeing Kilik's state she gave up her life, putting Dvapara-Yuga onto and saving Kilik. She turned berserk shortly after and Kilik himself killed her, impaling her through the heart with the Kali-Yuga.
