Anime: Starting from Blast Kengan

Yato Igarashi: "I have the strength I have today, all thanks to my own hard work. Others say I am the strongest fighting genius in history, the strongest creature, and the strongest man on earth. However, behind these three 'powers' lies my endless hard work. I am a hardworking genius who never backs down in the face of difficulties. You are indeed stronger than me, but I am constantly evolving... Deep Blue, give me some more!"... (This is a souvenir manga that blends a lot of well-known daily life anime. It tells the story of how a super-powerful man changes the style of youth romance beyond recognition. The main plot is Kengan 1 and 2, and 'for the time being' does not involve other fighting anime such as Baki and History's Strongest Disciple Kenichi...)
