風が変わる教室の窓
あの日の笑顔はまだそこに
砂浜の足跡 波がさらう
最後のアイス溶けていく
消えない記憶 手のひらに
Just one summer ただひとつの夏
駆け抜けた時間が胸を焦がす
次の季節 まだ見ぬ景色
でも心はここにある forever
花火の残像 夜空に滲む
隠した涙 誰も気づかず
自転車の影 夕日に伸びる
耳に残る波の音が
また呼び戻す 一瞬の夢
Just one summer ただひとつの夏
終わりが来ても消えない光
次のページ 書き足す未来
でもこの気持ち忘れない forever
Just one summer ただひとつの夏
駆け抜けた時間が胸を焦がす
次の季節 まだ見ぬ景色
でも心はここにある forever

On August 30, Ryu will release the compilation album "Just One Summer" featuring WINDY.
Following the July 2025 release of "Summer Sky", which achieved high streaming numbers worldwide, this new album was created in response to listeners' requests for "just a little more" and Ryu's own wish to hear more.
All 10 tracks are AI-generated, with original lyrics written by Ryu. Centered on the theme of summer, the album is inspired by WINDY, a fictional four-member high school girls' band. Built around the concepts of youth, dreams, and the future, the songs feature refreshing, fast-paced performances and vocal arrangements that reflect each "member's" individuality. Compared to "Summer Sky", the album offers a broader range of styles, arrangements, and lyrical worlds.
Blending rock and J-POP, the music delivers upbeat, catchy melodies with a cooling summer breeze. The cover artwork, also created using generative AI, visually captures the album's concept.
The pre-released tracks-"Just One Summer" and "HANABI"-were launched alongside AI-generated music videos on TikTok, already surpassing the previous album's views and earning positive feedback from listeners worldwide.
Artist Profile

Ryu started DTM in university and has been creating mainly songs that he wants to listen to. Based on J-POP, his songs feature lyrical melodies and carefully written lyrics about joy and sadness, combined with the natural singing of Hatsune Miku in a sad but easy-to-hear way. The song Groove of Love from his 6th album was used as a commercial song for the Spoon app.
