"Hope!! Once More Awaken in the Present, Trunks" (HOPE!! 再び - 現在で目覚めよトランクス, Kibō!! Futatabi - Imade mezame yo Torankusu) is the forty-eighth episode of Dragon Ball Super. Its Japanese air date is June 19, 2016.
Future Trunks is angry and distraught over the death of Future Mai, and wonders if he should run. Future Trunks notices the Capsule Corporation building is intact, realizing that Black does not know about the time machine. Black wonders why Future Trunks insists on fighting when he knows he cannot win. Frustrated, Future Trunks transforms into a Super Saiyan and attacks Black, successfully landing a few blows, but he is quickly beaten back. As Black prepares to finish the fight, Future Trunks finds his sword next to him and throws it to Black, who is distracted and his Ki Blast is destroyed. Future Trunks then fires a Masenko at Black, who blocks it, causing a huge smoke cloud. When the smoke is dispersed, Future Trunks is gone, as he had snuck into the Capsule Corp building. Future Trunks inserts the fuel into the time machine, climbing into it and starting it up. Black then begins to sense for Future Trunks' ki, noticing him in the time machine in the air. Black fires a Dark Kamehameha towards Future Trunks, but the time machine disappears right in the nick of time. Black is then surprised to find out that Future Trunks' ki has completely disappeared. As Future Trunks is traveling back in time, he recalls Future Bulma's words, and vows that this one-way trip will not go to waste.
Back in the present time, Trunks, Pilaf, Mai, and Shu are being taught mathematics by an instructor. Pilaf (in a complicated way, and according to the instructor, a way an old man would explain it) explains a math equation when Trunks did not understand it. The students are dismissed for lunch, and Trunks runs with Mai, holding her hand. Outside the Capsule Corp building, while he is eating lunch, Trunks senses a disturbance, and notices the time machine appearing. Trunks flies towards it, and looks inside, seeing Future Trunks unconscious, having succumbed to his fatigue. The instructor points out that the time machine is some Capsule Corporation craft, and Trunks is confused. Shu is instructed to go get Bulma, who races to the time machine, and realizes it is Future Trunks due to the word "HOPE!!" written on the side. Bulma lays an unconscious Future Trunks in a bed, and prepares to call for Vegeta. After she leaves, Mai and Shu wonder why Vegeta needs to be called, but as they realize that Trunks and Future Trunks look completely similar, they wonder if Trunks has a long-lost brother, which shocks Trunks.
In another room, Bulma is frantically looking for an item, revealed to be a communicator given to her by Whis. On Beerus' planet, Whis, Beerus, Vegeta and Goku are discussing the ramen they just ate, as Whis receives the call from Bulma. Bulma shows Vegeta and Goku the severely injured Future Trunks, and they are shocked. Trunks is even more surprised that the young man is also being called "Trunks". As Pilaf and the gang are wondering if Bulma and Vegeta are involved in a scandal, Bulma yells at them to be quiet. Bulma asks Goku if he has any Senzu Beans, and Goku says he does not. Vegeta tells him to teleport to Korin Tower to get some, but Goku says he cannot sense Korin's ki as it is too far away. Vegeta says they will first teleport back to Earth, and asks if the "younger" Trunks is there. Bulma instructs Trunks to power up so Goku can lock onto his ki, and the young Saiyan does so, transforming into a Super Saiyan. Beerus and Whis, interested, also tag along. After they arrive, Vegeta immediately tells Goku to go get some Senzu Beans. The instructor, surprised at all of these events, fearfully goes home, claiming she "has a headache". In the alternate timeline, Black vows to find Future Trunks, and powers up, coating a dark-colored aura.
At Korin Tower, Korin and Yajirobe play limbo, as Goku arrives and grabs the pot full of Senzu Beans. Yajirobe asks Goku if he wants to play, but Goku says he is in a hurry, and teleports back. Bulma feeds Future Trunks a Senzu Bean, and he eventually opens his eyes. As he sees Goku and hears his voice, he begins to have flashbacks of Black, and the deaths of Future Bulma and Future Mai. Suddenly, an angry Future Trunks jumps out of bed and attacks Goku, surprising everyone. Goku is also surprised and confused as he blocks the attack.
