Heartwarming / Sakigake!! Otokojuku

• J preforming the Spiral Hurricane Punch, the same move that his father used to save his life from a fire at the cost of his own life, to defeat Bo Feng. After he does so, he thanks his father with a proud smile on his face. It crosses over with Awesome Moments as well, due to it instantly defeating Bo Feng and leaving him embeded in a wall after he spent a majority of his fight with J casually beating him down like he was nothing.
• The graduation scene at the end of the series is probably the heartwarming equivalent of Mundane Made Awesome, due to everybody, even the most stoic and reserved of the students, such as Akashi Gouji, Gekkou, Raiden, and Hien, crying Manly Tears of Joy. It even manages to make Edajima Heihachi's signature catchphrase into something that's genuinely touching by making it seem like he's not only addressing his students, but the reader as well.

  Toramaru Ryuji: "Th...This school was like hell, with harsh training every day...!!! I...I've wanted to quickly run away from here even for a day, and yet...!!! It all seemed like it was yesterday..."

  Edajima Heihachi: "This is my final farewell gift to all of you!! I AM THE PRINCIPAL OF OTOKOJUKU! EDAJIMA HEIHACHI! THE END!!!"
