◇ Personality As the young master, he constantly looks out for guest satisfaction above all else. Because of this, he is strict with both himself and others, never neglecting the training of his staff. In his private life, he tends to become surprisingly sloppy regarding his own affairs.

◇ Personality Talkative, friendly, and loves children. The type who doesn't sweat the small stuff. He enjoys being relied upon.
Mahiro Hiwatari
19 years old | 176cm | First person: I (polite) / Second person: you (polite)

Madoka Tsurugi
26 years old | 189cm | First person: I (rough) / Second person: you (blunt)
◆ Profile The bassist and lyricist for the popular band "Krone." Because progress on their new song is poor, he is staying at Hosui-so on his manager's orders, essentially confined to his room. While he thinks, "I'm at a luxury inn, I want to play and sightsee!" he groans at his desk for the sake of the fans, soaking in the hot springs to change his mood. Hobbies are shogi and cooking.
◇ Personality He acts like a "king" in front of fans, but at his core, he is a very sensible person. He often gets fed up and snaps at the pace-setting Nozomi. He is polite to the Hosui-so staff.
Nozomi Misono
22 years old | 179cm | First person: I (soft) / Second person: you (casual)
◆ Profile The vocalist and composer for the popular band "Krone." He is staying at Hosui-so with Madoka, who is stuck on lyrics. A so-called genius type, he works silently on music while waiting for Madoka's lyrics to be finished. Occasionally, he wanders around Hosui-so or nearby tourist spots to enjoy a brief, leisurely rest. Hobbies are sleeping and watching movies.
◇ Personality He has few emotional ups and downs; Madoka calls him a "stone-faced man" due to his lack of expression. He is very direct and doesn't sugarcoat things, so he often sounds harsh.

Intro
You are swayed by the movement of the taxi, looking out the window at a building that is wooden yet grand in construction.
―― Hosui-so.
That is the name of the luxury ryokan, limited to ten groups per day, where you are headed.
Stepping out of the taxi, you are greeted by a stately building radiating the warmth of wood and a garden colored by the plants of the four seasons. Soft lights spill out beyond the stone path, quietly welcoming visitors.
You readjust your bag, place your hand on the heavy wooden sliding door, and slowly pull it open.
