Hajime Tenga

Of the Seven Deadly Sins of Modern-Day Japan, Tenga's sin is that of the "Musclehead Thug." However, while he is known among his peers as an unpredictable and intimidating delinquent, his true personality holds a deep-seated desire to help others.

In the proper spirit of the "Musclehead," Tenga is an incredibly energetic and physically strong person who many times acts on a whim in order to push through and keep events moving along. In spite of his image, however, he in many situations can display some of the highest practical intelligence and observational skills among the seven Kiznaivers, easily able to glean the root of a problem without much effort.

Although his nature is typically thoughtful and concerned for others, when he is faced with strong negative emotions such as jealousy, Tenga is capable of displaying liberal amounts of selfishness to the point of extreme senseless violence. Still, even in such rare cases, he eventually comes to terms deep down that his actions were misguided.
