Template:Chapter Infobox Overwhelming is the 400th chapter of Akira Amano's Katekyō Hitman Reborn!.
Synopsis
Jager mocks the Green Mosca and Verde calls him a bad loser. Jager attacks by short warping his hands, causing Green Mosca to malfunction due to the detection of multiple heat sources. The disembodied hands slice through Green Mosca's arms easily and it falls to pieces. As Verde steps out, Jager says that he will spare him because killing Arcobalenos is not his motive.
Troubled, Reborn wonders what is Jager's weakness. Jager moves on to his next target, Mukuro, and appears behind him. Mukuro attempts to block the assault but his trident breaks and he is injured. Jager comments that the damage inflicted is too shallow and prepares to stab Mukuro again but finds his hand bind by Dino. However, by short warping and leaving his hand behind, Jager slashes Dino's torso. Jager's hand escapes the bullwhip and heads for Dino's face but it is deflected by Hibari, who tells Dino that he has repaid his debt. Hibari attacks Jager but he dodges. Reborn wonders why Jager did not make use of his short warp. Hibari and Mukuro reveal that they had noticed too. However, Jager comments that his short warp has no weakness.
Hibari and Mukuro conceal themselves behind the multiple spheres created by Hibari. Jager’s attacks prove to be useless due to Mukuro’s flame decoys. Hibari finds a chance and attacks with the same technique he used earlier. However, it did not work as Jager is able to short warp and he reappears behind Hibari. Before Jager's attack could land, he is punched in the face. Tsuna has arrived and is enraged at seeing his fallen comrades. Tsuna's flames grow as he prepares for battle.
