Akai Kajitsu

This title song was written as the theme song for the television series Key Person of Interest Detective starring Yuta Tamamori, and the title means "truthful truth, true heart."

The music video (MV) for the song was shot on location in a medieval European-like town in Wakayama Prefecture,{{cite web |title=Park guide |url=https://www.marinacity.com/porto/guidecat/photospot/ |website=Porto Europa |publisher=Wakayama Marina City Co., Ltd |access-date=2024-05-31 |language=Japanese |date=2017}} the first time in three and a half years since "3.6.5".

The "Short Movie" is a story version and the "Dance Edition" is a dance version of the same song with the same arrangement. Short movie depicts the story of the "revolution" of seven people trapped in a world where music is forbidden, until they are freed, while in "Dance Edition" the seven people are handcuffed and dance the "chain dance". The use of chains was inspired by the aforementioned drama starring Tamamori and proposed by member Kento Senga.{{cite web|title=キスマイ、"鎖ダンス"MV2種類にファン歓喜 藤ヶ谷「僕たちで玉森を救いました」|url=https://www.oricon.co.jp/news/2100326/full/|date=November 14, 2017|publisher=oricon |access-date=27 April 2024}}

The song depicts "seven people deprived of their freedom and bound together" and "the way seven people are connected by a bond". The members also wear chains in the jacket photo and when they perform the song on TV.{{cite web|title=Kis-My-Ft2は"型を突破"する時を迎えている？ 「赤い果実」パフォーマンスから読み解く|url=https://realsound.jp/2017/12/post-133853.html|date=December 1, 2017|publisher=oricon |access-date=27 April 2024}}

She also commented that the phrase "Akai Kajitsu" that appears at the beginning of the song and after the first chorus accentuates the song and gives it a powerful impression, making it more than just a "dark" song. She also commented that She felt a musical quality in the part after the second chorus, which has no lyrics, and that he felt the group's new appeal in that it portrays "them as characters in a story rather than their life-size, realistic selves.{{cite web|title=Kis-My-Ft2「赤い果実」で打ち出した新たな側面 "演じながら歌う"楽曲スタイルから考察|url=https://realsound.jp/2017/12/post-137109.html#google_vignette|date=December 9, 2017|publisher=oricon |access-date=27 April 2024}}
