Mission 25: Pursue the Mystery of the Avatars! (アバターの謎を追え！ Abatā no Nazo o Oe!) ) is the twenty-fifth episode of Tokumei Sentai Go-Busters.
Masato's ghost stories during Obon scare Yoko, and the arrival of Rousokuloid and his dream altering powers only make things worse.
It is Obon, and as Masato's ghost stories freak Yoko and the Buddyloids out, Ryuji confides to Kuroki of his concern about the nature of Masato's avatar. The next day, alerted to a Vaglass Megazord arriving within 52 minutes, the Go-Busters arrive to the Bakuta district to find a group of people having nightmares as the Metaloid Rousokuloid reveals himself to be the cause. During the fight, Rousokuloid tricks the Go-Busters into looking at his flame, causing them to enter their own nightmares. Rousokuloid takes his leave before being hit by Masato as he and Jay transform to snuff out the Metaloid's flame to cancel the nightmares. His victims wake up, save Red Buster, whose nightmare was of a giant chicken and is rendered immobilized. Learning that death in a nightmare means death in real life, Ryuji attempts to have Masato reveal the truth about his nature. However, Masato instead tells Ryuji that becoming strong enough to enter subspace should be his concern. Soon after, the Go-Busters are alerted that Rousokuloid is attempting to use the local television station to broadcast his hypnosis across the airwaves. When they arrive at the station, Escape makes her presence known. Blue Buster fights her, hoping she might give him answers, while the others deal with Rousokuloid. However, upon seeing that getting answers from her is not going to happen, Blue Buster purposely overheats himself and gives Escape the fight she desires as the Rousokuzord arrives with the CB-01 Cheetah fighting it and the Bugzords. After Yellow Buster and they finish Rousokuloid off, Beet Buster and Stag Buster use Buster Hercules to finish off the Rousokuzord. Blue Buster manages to defeat an astonished Escape, as she leaves satisfied just as he loses conscious. As the sun sets, Masato accepts Ryuji's way of fighting, despite still having issues with his avatar's state. Upon learning that Hiromu overheard him and Kuroki, Ryuji reveals that there is a chance that those who end up in subspace may have lost their physical forms, and Hiromu assures him that they will find the truth.
