The 11th round of the feature tours has Kuguri taking on the role of main host.

A unique collaboration request then comes from a world-famous piano manufacturer in Hamamatsu, directly addressed to him. The proposal specifically asks for "Domeki Kuguri to participate in a piano competition."

Upon hearing this, Raito volunteers to take his place and compete as Kuguri's apprentice— offering to become Kuguri's arms. Despite everyone thinking his idea was a long-shot, Kuguri agrees, with ulterior motives in mind. Thus begins a twisted master-and-student relationship, which Kuguri saw as nothing more than a little game. However, the situation takes a turn once he discovers that his mother is involved in the competition.

Much like a seesaw, the two are constantly out of sync with each other. Will these reflections somehow be able to meet.....? And will they be able to bring ruin to this former "God"?

*Recommended to read Kuguri's season 1 and 1.5 novels before reading this event! (Novel 1 is ESPECIALLY important.)

Kafka and Renga are both dog lovers. The perfect job opportunity for this pair came along R1ze's way – which was a collaboration with the police dogs of the HAMA Police Station! Kafka was appointed to be the "One Day Police Chief". The members of R1ze are also set to hold a special performance with the department's police dogs. With these police dogs staying over at HAMA House in preparation for the event, the residence becomes even livelier than before. However, how will Shuumai, their resident house dog, react….?! Meanwhile, Kafka receives some unsettling information from Sakujiro. There appears to be a certain criminal group wrecking havoc as of recent, and are planning to cause trouble on the day of the event!

Part 2 of the 1st Anniversary event!

HAMA Tours receives a request to "save a struggling hot spring inn" — which turns out to have come from Ejimura-san, the previous owner of HAMA House! The task is heeded by the hot springs loving duo of Chihiro and Yodaka; along with Ten, Kuguri, and Ryui who would be in charge of the 'harsh critiques'. Thinking that they got lucky, being able to simply soak in the hot springs for work, they felt a happiness that was quite short-lived. They found themselves in a bizarre inn that was filled to the brim with Ejimura-san's odd tastes—?! ☆★☆

As the year was coming to a close, Renga and Chihiro were called to the HAMA Tours meeting room -- wherein they were offered to appear on the year-end special of the popular TV show "Celebrity Ranking Battle Royale"!
