Important things that happened
- Since Yuuto uses ZeroLiner, Owner believes he is also a protector of the flow of time. Ryoutarou should listen to his warning and stay away from the past Sakurai Yuuto.
- Owner says the ZeroLiner should have been destroyed along with that erased time of the future.
- Yuuto transforms into Kamen Rider Zeronos Altair Form.
- When possessed by Deneb, Zeronos transforms into Kamen Rider Zeronos Vega Form.
- Although Yuuto keeps telling Ryoutarou that he should stop, Ryoutarou replied with what Sakurai-san taught him: Even though he's weak, have bad luck and doesn't know anything, that's no excuse for not doing anything.

Contract holder's Memory
- March 12, 2006
- Haruka (Amano's fiancee) was ill, but never told Amano about it. To leave something behind for Amano, Haruka buried a time capsule while Amano stood watch. A year later, Haruka went into surgery for her sickness and never wakes up again. Amano tried to find the time capsule, but he cannot remember the buried location.
- Den-O's intervention
- Ryoutarou left a mark on the buried location when chasing the Imagin to the past. When he returned to the future, he digs up the time capsule for Amano. Inside it's revealed to be the pair of boxing gloves that Amano threw away. Amano was a boxer back then, but he gave up on boxing so that he could have a stable life after marring Haruka.
- There might be other rail-lines beside DenLiner and ZeroLiner.
- Ryuutaros says that just like Ryoutarou, Yuuto has the smells of Airi.
- Deneb cannot stand winning through unfair means.
- Altair, Vega, and Deneb form the astronomical asterism Summer Triangle that Airi likes.
- Yuuto headbutts Deneb, but it hurts Yuuto more since Deneb is hard as metal.
