Naoki and two young girls

Naoki and Chinatsu Amakawa were second-year classmates at Fujibayashi High School, and they were cousins and had a childhood engagement. The engagement was later dissolved, but Chinatsu still habitually called herself his wife. Kasumi traveled from afar to Fujikawa, using Naoki's future as a bargaining chip to demand a stay, making his daily life difficult to maintain.

They met at school

The new math teacher, Hoshizuki Orihime, is relatively short and often asks Naoki to help clean the blackboard, earning her the nickname 'Teacher Hime' among students. First-year Kodo Shimei, Naoki and Chinatsu have known since middle school. She enjoys campus news and photography, and beneath her lively demeanor, she also has a serious side in her work.

When Naoki was feeling unwell, Chinatsu came to pick him up and found that Kasumi was already living with him. She immediately called her father, only to learn that he had long known and had given permission. Chinatsu then announced that she would move in as well.

The timing added by the original system

In a discussion published in 2026, Shibata recalled the 2010 Xbox 360 original work, where Chiyomaru Shikura requested the addition of a new selection system. The team added the 'Yubikiri Trigger' when the game was already quite complete.

Character names must also be approved by the producer; The director's proposal was finalized after repeated rejections and alternative proposals. The birthday was set late, so the team tried to avoid birthdays of existing characters in the series.

Evaluation of achievement proposals

The achievement proposals proposed by the director were reviewed by members familiar with the achievement system within 5PB, who would reject inappropriate proposals and provide suggestions for modifications.
