==Errors==
*When Sento and Ryuga equipped their Build Drivers, Ryuga's Fullbottle Holder isn't seen. However, in later shots his Fullbottle Holder is seen on the right side of his belt.
*When Shinobu does his on-screen transformation into RabbitTank Form, his Build Driver announces "Hagane no Moonsault", even though it should be impossible, as that announcement was only added by Sento into his own Driver some time after his first time as Build (the phrase was also not heard in episode 13 during Sento's flashback to his first transformation).
**Further supporting the above being an error, is that earlier in the episode, it is shown that none of Shinobu's other Best Match forms have their personal phrase.

*This is the first episode since its debut that Evolto does not transform into Kamen Rider Evol.
*This is the first time Sento transforms directly into Build TankTank Form.
*When Sento and Ryuga equip their Build Drivers, an additional sound effect is heard. In Kamen Rider Zi-O, that additional sound effect is exactly the same sound the Ziku-Driver makes when the user sets the Ridewatch into the driver. This will continue on in later episodes, Be The One, and Prime Rogue.
*This episode features the debut of the CD Lost Fullbottle.
