Kugayama Shiori's Death Method Diary: Original draft
In 'Kugayama Shiori's Death Method Notebook,' Fumi Kazuki was responsible for the original draft.
The daily dialogue and atmosphere of the original second game
In the 2018 original edition of '9-nine: Sorairo Sora Utasora no Oto,' Fumi Kazuki focuses on everyday dialogue, hoping to maintain a light, readable feel even in serious development; Shinkaiten's bright personality also became a key point in lightening the atmosphere.
Natsuno's final exit
Kazuki Fumi submitted two projects to CUBE that fit the brand's style and were close to her personal tastes; the latter was ultimately selected and developed into "Natsu no Shujiki."
Single-line conceptualization and branch selection
Fumi Kazuki recalled that "Natsu no Owari" was initially conceived as a single-story storyline, later considering more complex branching structures to increase gameplay content.
The protagonist's personality and empathy
In 'Summer of the Last Extinction,' Kazuki Fumi balances the protagonist's own personality with the player's empathy, and uses a single female lead structure to focus on their relationship.
The freedom and constraints of original artwork orders
The key animation commission for Natsu no Tsukiki deliberately left room for the artist to shine, and Kazuki Fumi didn't completely kill the exterior; He also requested three sets of casual wear to avoid having the same outfit on two consecutive days.
Transitioning the prologue of the publicity
Kazuki Fumi wrote a new prologue for Natsuno's End-Extinction promotion, avoiding obvious dates and other external time information, so this new text could be accessed in the trial version.
Low-price continuous cropping with a volume structure
Kazuki Fumi accepted an invitation to write a series at a low price and participated in the planning and script of 'Criminal Border.' Before the release of the first volume, he explained that each volume focuses on a single female lead, making their relationship clearly developed within that volume and allowing the main story to continue in subsequent volumes; He explained this structure by using different seasons of overseas TV dramas.
Invitation and design communication for 'Summer Ends'
Fumi Kazuki recalled that when he asked, 'Hibikino-san's family is an eroge shop!' After receiving permission to livestream the trial version, I received a private message from Katahito and soon received an invitation to write. Katahito added that he originally wanted to hire him to write a script for Sonora at the right moment, but his boss first commissioned CUBE for a new project, which later evolved into 'Summer End.'
Fumi Kazuki explained that the title "Natsu no Tsuwa Tsuki" was chosen by the brand; he first received the name "Natsu no Tsuki" (Summer no Tsuki), then learned that the last character had been changed to "Kei." When reviewing character designs, he compared several proposals received and clearly expressed his preference for Mio's wavy hairstyle.
