Battle Tendency - Chapter 45 
Caesar: A Lonely Youth, Part 2 (シーザー孤独の青春 その②, Shīzā Kodoku no Seishun Sono 2), originally Caesar: A Lonely Youth (シーザー孤独の青春, Shīzā Kodoku no Seishun) in the WSJ and tankobon releases, is the forty-fifth chapter of Battle Tendency and the eighty-ninth chapter of the JoJo's Bizarre Adventure manga.
At the age of ten, Caesar's father, Mario Zeppeli, abandoned his family, despite being considered a trustworthy and loyal family man. Caesar was distressed by his father's abandonment, and all the money he was left with was stolen by Caesar's second cousin. Afterward, Caesar became very violent and was sent to a poorly operated orphanage. Caesar later ran away, becoming a dangerous criminal committing countless crimes (but never murder). What truly made him dangerous was his Ripple ability that he was unaware of at the time. One day Caesar saw his father, and followed him into the basement of the Colosseum with revenge on his mind. Caesar found the wall containing the Pillar Men and touched a gemstone embedded into the wall. Mario pushes Caesar away, getting absorbed by the wall in Caesar's place. Mario, unaware that he is facing his son, tells Caesar to report his death to Lisa Lisa and that the men in the wall will soon awaken. After being told this, Joseph now understands Caesar's desire for immediate action, and decides to join him in the fight.
