Hongō Kazuto (北郷 一刀)
Visual novel version
The main character of the visual novel series. He is a modern day Japanese student who was trained in kendo, military strategies and has pretty good knowledge about Asian History in general. He was sent back in time to ancient China when he attempted to stop a mysterious student from stealing an ancient Chinese mirror within the school's collection and ended up breaking the mirror in the process. Due to his abnormal costume (his school uniform) and manner of speech (English words), he is saved by Kan'u and is mistaken to be the "Messenger from Heaven" who is said to be able to bring peace to China. He initially denied and turn down the role but later on decides to aid Kan'u in her quest, hoping to find his way back home.
In Shin Koihime Musō, regardless of which kingdom is chosen, Kazuto is sent to the other world when he was sleeping back in his own world. Usually before he is found, the lords of each kingdom comment how they saw a shooting star in the sky. Like in the first game, he is still considered the Messenger of Heaven.
He is often shocked as to how heroes he knows from literature are so very different from what he has learned from his time. In the first visual novel, his role is akin to Liu Bei. However, he will take an entirely new role in the upcoming remake, as Liu Bei has become a separate character. In the remake, Kazuto can ally himself with any one of the warring factions, becoming the main partner of either Ryūbi, Sōsō, or Sonsaku.
