A translation of the original concept inspired by 'You Who Replace Memories.'

The in-house original concept for 'Memories Replace You' carries a TV drama-like character impression. Yukihiro Matsuo and Takayuki Koshimizu collaborated to turn these ideas into character designs for the series; The original design featured magazine-style poses, clothing patterns, and material expressions, and the two needed to transform them into game characters.

The art style of the "Kara" series is well coordinated

The drama-style direction of 'Memories Change' fell short of some players' expectations, so when making 'Sorera', Matsuo and Koshimizu rereferred to the previous two works. The focus of coordinating character design is to balance the entire work, ensuring that all characters are placed together while maintaining a sense of unity within the series.

From dating ADV to scientific ADV

Matsuo will play "CHAOS;" HEAD" is seen as the starting point for his entry into scientific ADV. Previously, he continued to produce romance ADVs; Shikura incorporated real-world science and theory into his planning concepts, prompting him to rethink how ADV is produced and presented.

Storyboarding, layout, and character corrections

Matsuo tends to have storyboards first, then develop the image creation. 《CHAOS; In 'CHILD,' Kanji Wakabayashi first checked the layout of the scene, followed by Matsuo making character corrections; He also handles character design beyond the uniform and Sasaki roles.

Extracting supporting character styling from the script

Matsuo uses Sasaki's main character art style as a model, and then expresses the unique traits of the supporting characters according to the script. Gen's top hat and cane are inspired by the 'aristocratic game' setting in the script.

Aozaki Yume was added for the plot

Aozaki Yumehara does not intend to create character images. After the script was needed, the team invited external key animation designers based on Ruolin's storyboards; Matsuo further revised her appearance to avoid overlapping with Nono's look, adopting a short-haired look.

The transition between the original manuscripts and digital images

Matsuo recalls that when "Memories Off" was made in 1999, KID had not yet formed a fixed division of roles between key animation and coloring, so those who could draw would collaborate to create new artwork. There is no fixed size standard for character illustrations; the team referenced past transplanted works to explore the correspondence between original artwork sizes on paper and digital import sizes.

Reconfirmation of the second-generation color scheme

"Memories Off 2nd" retains Mutsumi Sasaki's design but paints the characters' hair and skin tones even darker. Matsuo recalled that the impression between the old and new works was obvious, so he once asked the director to confirm whether using this coloring was appropriate.

After the company went bankrupt, he continued to draw encores

In a discussion published in 2026, Matsuo recalled that when KID went bankrupt, "Memories Off #5 encore" was still in the key animation production stage. While the staff were dealing with the question of how to continue the project, they were still working on the sketches.

Point map input for the NeoGeoPocket version

Matsuo recalled that the NeoGeoPocket version of the "Memories of Autumn" series was first drawn with original artwork, then internal staff created pixel art based on it. The team used a system that could be used to control the game with the arcade joystick, and the sound of joystick operation kept echoing throughout the company during production, leaving a strong impression on him.

Pose proposal for the original Ever17 male character art

Nakazawa recalled that KID often used the standing posture from character design drawings as his basic character pose; In 'Ever17', the male character illustration designed by Yukihiro Matsuo changed his pose. Matsuo proposed a plan, which Nakazawa approved and adopted, including the image of placing his right hand behind his head. Nakazawa explained that this pose is taken for visual effect and does not have any additional plot meaning.
