Let's Live on a Transmission Tower, Part 5 (鉄塔に住もう その⑤ Tettō ni Sumō Sono 5), originally Reflecting Energy! (反射するエネルギー！ Hansha Suru Enerugī!) in the WSJ release, is the four hundred second chapter of the JoJo's Bizarre Adventure manga. It is also the one hundred thirty-seventh chapter of Diamond Is Unbreakable.
Josuke and Toyohiro face each other within the infrastructure of the electrical tower, leaving Toyohiro no choice but to fight to the death with Josuke. Josuke sends Crazy Diamond to punch Toyohiro, but the latter uses his superior agility to stay out of range. Now above Josuke, Toyohiro tries to spit on him, disgusting Josuke, but this move is merely a distraction for the scratches Toyohiro made to the tower.
The damage is reflected toward Josuke, but Crazy Diamond effortlessly parries them. Yet, Toyohiro sent his attacks so that every parried cuts would be continuously reflected within the tower and still end up toward Josuke. Unable to predict where the next attacks will come, Josuke is hit several times and is sent flying. Although he manages to hold onto a beam, he is in a precarious position and Toyohiro uses that opportunity to taunt him. However, Josuke reveals that he repaired the damage he received, and Toyohiro is struck in the face by the same damage.
