Soul Skyheart is a character that appears in the original Mugen Souls and Mugen Souls Z.
| ~ This young man is Sun World's hero.
Skilled in both blades and magic, he is the quintessential hero. He can come across as a bit brusque and taciturn, but it is all to remain level-headed.
He's fairly self-absorbed and tends to choose the archetypal 'heroic' way of doing things. In the midst of all that, he takes special joy in dressing up female party members in bikinis and forcing them to journey with him like that.
For that, and other reasons, his strength is highly praised, but the citizens find his interests creepy. This causes his popularity to suffer.
This guy is the first hero that Chou-Chou finds. They discover him breaking in villagers' houses and breaking vases. Chou-Chou and Altis believe that he's a criminal but Ryuto explains that Soul is actually a hero - a hero that takes too many perks in being one. Chou-Chou, Altis and Ryuto bump into Soul again later on and find him parading Sandy around in a tiny bikini. When Chou-Chou's efforts to make Soul a peon fails, Soul quickly transports himself to the castle with Sandy.
The next time Chou-Chou bumps into Soul, they both encounter the demon lord. Soul strikes the demon lord with one powerful hit. But then in pain, the demon lord merges with Sandy. Soul refuses to attack the demon lord so Chou-Chou does instead. When the battle is over, the demon lord disappears but part of it is still inside Sandy which causes her personality to change a bit. Chou-Chou then turns into CC Sadist to make Sandy her peon and the puts on a bikini to make Soul her peon.
Mugen Souls Z
| ~ "The former hero of Sun World who has an unfortunate obsession with bikini-clad women. If you can get past that little issue, he's a hero among heroes who is a master of both sword and spell. He fully embraces his status as a hero, and constantly tries to use it to get the girls around him into bikinis. He became more reserved while he was under Chou-Chou's rule, but has recently begun acting more like his former heroic self.
In Mugen Souls Z, Soul is dropped off at Amethyst World and assigned the task of taking over the world, like everyone else. After reuniting with the rest of the group, Soul is seen weakened by Supra, the ultimate god of that current world, and being chased down. The group attempts to help out Soul by fighting Supra, but they discover that their attacks seem to have no effect on her. Soul uses Flash magic which temporarily blinds her while the group makes a temporary retreat. After putting a safe distance between themselves and the god, Soul tells the others that he intends on settling matters with Supra alone (The original members of the party figure out Soul's intention while the new members are confused about what could be so important to Soul).
After leaving the group, Soul confronts Supra with the intention of using force in order to deal with her. Supra starts to get weak (thanks to the group who weakens her ties to the world) and accuses Soul of relying on underhanded techniques to defeat her before summoning her ship to attack. Using G-Castle to defeat her ship, the group reunites with Soul, where he reveals that the main reason for Supra's intense hatred towards him was because of a bikini (She refused to wear one since she was a mermaid and believed that it would be ridiculous for her to put one on). The group ends up battling Supra, who's legs change into human ones as a result. Soul finally manages to convince Supra to wear the bikini as a result, and faints from exhaustion.
Afterwards, Soul's role appears to be keeping Supra check as the god appears to have a crush on him.
In terms of action, Soul happens to be the most heroic hero in the game but in terms of personality, the complete opposite. Although he's great at taking out the bad guys, that doesn't excuse the fact that Soul is a swimsuit fetish. It's his ultimate weakness. Whenever he sees a girl in swimwear, he usually gets a nosebleed (in Japanese anime whenever a person gets a nosebleed it means they are seeing or thinking something perverted.) Soul maintains his hero personality by acting cool.
