The Record of Ichijo Kanesada's Struggle

Tanaka Keita, an ordinary college student living in modern Japan, gets hit by a truck whose driver had fallen asleep, but when he opens his eyes, he finds a gentle-looking bearded man with blackened teeth standing before him. "Oh!! Your eyes are open!" the man says, but the protagonist has no idea what he's talking about and immediately feels like crying... It turns out that he has been reincarnated as Ichijo Kanesada, a historical figure who ranked dead last in all abilities in history games and is described as foolish in historical records, and that he has been reborn into the Ichijo clan in 1543... This is my first work and submission. Since I'm still inexperienced, there may be typos, omissions, and contradictions, but please feel free to write any comments or corrections you have. I will refer to them for my future work. (Please refrain from abusive language.)
