S05E152 — A Boss' Resolve

Verde demands Tsuna and his guardians to surrender the Vongola Ring in return for the Arcobaleno's lives. Tsuna refuses to compiles as the rings will be needed for the future battles and declares they shall defeat Verde and save the Arcobaleno. Verde uses a machine and absorbs their flames and uses it to power his box weapons. Unable to utilize ring flames, Verde begins to overwhelm them. Tsuna and his friends regain their resolve and are able to utilize the ring flames to gain the upper hand. When Tsuna destroys the machine emitting non-trisette rays, Verde seemingly kills the Arcobalenos by self destructing his robots. Reborn reveals that the Arcobalenos who were captured by the robots were illusions and that they were waiting until the non-trisette rays dispersed. After Verde's defeat, it is revealed to be a robot and Verde is hiding elsewhere.
