Since Vladislaus has finally awakened and Kaiju was able to store another treasure to be used for the secret technique later, he had decided to enter Vladislaus' castle.
Kaiju would rather call it castle than burg due to its grandiose, classical appearance. Furthermore, the very fact it appeared old suited for the owner of the castle, a vampire.
Despite the advance technology, Kaiju could only watch movies at school, and he was able to watch a movie made prior to the appearance of Tower. Just sauntering in the hallway made him feel like an actor in the movie, and he couldn't help but act like it. Snow and Little Gorilla gave him strange gazes but Kaiju ignored them anyway.
Kaiju enjoyed his leisure walk, even though the cobweb and insects crawling at every nook and crook–unable to be undetected with Kaiju's night vision–made the place creepy, nevertheless, Kaiju enjoyed every moment of it.
