(Imagine if Hikaro, Sento and Banjou are inside)
Inside the cafe, Hikaro then told Sento and Banjou about his life back on Earth and how he likes Kamen Riders since the year 2000. Both of them are impressed but was interrupted by Misora who came in.
Misora: Sento! Banjou! *shocked* There is a strange monster attacking Shozu park!
without hesitating, Sento and Banjou then rose up and was about to go when Hikaro tagged in.

The four of them then saw Woz, who appeared out of nowhere, coming in the fray.
