With no timeline to call her home, Hana is filled with malice and spite towards the Imagin, making her capable of subduing the Tarōs when they get out of line, especially Momotaros with a simple punch to the head with force equal to a truck's.

Unknowingly, his attempt to hypnotize Ryotaro in hopes of exorcising the evil spirits result in Ryutaros revealing himself.

As he is Yuto's future self, Sakurai has access to the Zeronos arsenal. Eventually, the memory of Sakurai is completely erased from mostly everyone within Ryotaro's time. This happens because Sakurai provided Deneb with the first set of Zeronos Cards Yuto uses at the cost of his future self's existence, with the final Zeronos card presented to Yuto in the final battle completely erasing him from time.

A large  majority of Imagin serve Kai, arriving to the year 2007 to find weak-hearted humans to form contracts where they fulfill the hosts' desire at any cost. Once the contract is fulfilled, the Imagin uses the host and their memories to go back further in time as part of Kai's orders to seek out the , and destroy him to restore their future.
