Caesar: A Lonely Youth (5) (シーザー孤独の青春 その⑤ Shīzā Kodoku no Seishun Sono 5?), originally The Crimson Bubble (鮮赤のシャポン Senseki no Shabon) in the WSJ release, is the ninety-second chapter of the JoJo's Bizarre Adventure manga. It is also the forty-eighth chapter of Battle Tendency.
After the Holy Sandstorm, Caesar lays on the floor, covered in blood. The mansion around him crumbling from the powerful attack. Wamuu falls down, praising Caesar for his brilliant fight. However, at that moment Caesar rises and makes a last pitiful attack on Wamuu. After relentless weak attacks, Caesar finally grabs the antidote for Joseph, fulfilling the Zeppeli's legacy of dying for someone else. Caesar uses his final Ripple to create a bubble made of his own blood, containing the antidote and Caesar's headband. Caesar then gets crushed by the falling debris of the mansion. To honor the magnificent warrior, Wamuu leaves the bubble containing the antidote alone, and retreats further into the mansion.
