Ichiban Kasuga

Ichiban Kasuga is one of the two main protagonists of Yakuza series starting at Yakuza 7.

Personality
Kasuga is a fiercely loyal and steadfast individual, perhaps to a fault. He wears his heart on his sleeve and is prone to letting his emotions get the best of him, whether it be sheer rage or getting overly excitable. However, he has a strong sense of justice and is always willing to help out anyone in need. Kasuga is also a huge fan of Dragon Quest, a video game he loved to play ever since his youth. This contributed to his strong sense of imagination where he imagines his battles as if they were a turn-based JRPG. This imagination has also made him a quick thinker and a creative tactician in battles despite his rash and impulsive demeanor.

One of Kasuga's notable traits is his unfailing kindness and general love for people. These traits have made him an infectiously charismatic person that never fails to inspire admiration from the people around him. He cares deeply about his party members and leads them with grace and in turn, they stand by him and are ready to have his back no matter how overwhelming the odds are.
