Night Raid is the 101st episode of the Katekyo Hitman Reborn! anime.
Tsuna and the others prepare for their attack the next day. They've been given Auto Mammon Chain Ring Covers for their Rings, Dying Will Clothing and a communication system. Meanwhile the Millefiore squad digs their way underground and ends up at where the transmitter was. It turns out Hibari noticed the transmitter and carried it there to lure the Millefiore members away from the base.
