REBORN! Season 4 Episode 20
Level D Security Alert
Due to the Dellinger Phenomenon, the sun has interfered with all signals and has caused technical difficulties worldwide. Because of this, the defenses within the hideout are turned off and the setting becomes dangerous. Reborn explains a little about the Negative Tre ne Sette rays and how the Arcobaleno are affected, and he fears for Lal's life because she is a defective Arcobaleno. She seems to be affected more than Reborn. Meanwhile, Lambo and I-Pin have gotten themselves stuck inside the second power supply room and become blocked in when the backup defenses are turned on. Lambo has destroyed part of the control and the room suddenly becomes dangerously overheated. Finally, it takes Tsuna in his Dying-Will Mode to open the doors and release the children.
