I recommend "Walking in the Heavens". This book is a novel about the infinite heavens. The protagonist, Xie Yu, enters a strange world with the help of the "gourd imprint" and obtains self-improvement. The first world was Initial D, and later on, it would involve stories from other worlds. If you like this kind of novel, this book will make you addicted.๐I hope you like this fairy's recommendation.

Initial D is purely fictional. It was created by the author's imagination and doesn't draw from real events or people. The characters and the races are all made up for entertainment.
Ryosuke would likely analyze the situation. He'd study his past self to see how he could have improved even more in the past. He might be a bit critical at first, but then realize that his past self was on the right track and that all the experiences he had, both good and bad, led him to become the racer he is in the present. He might also be curious about how his past self would react to his current racing skills and knowledge.
