[Kagerou Project] A roundup of popular songs from the Kagerou Project series (1–10)
Headphone Actorjin

With razor-sharp guitar and a heavy, thudding bassline, this track is irresistibly cool.
Released in 2011, “Headphone Actor” is a piece that features Takane Enomoto—a character from the novel Kagerou Daze II: a_headphone_actor—as its protagonist.
Its lyrics project a decadent atmosphere inspired by the game world depicted in the story, perfectly matching the song’s stylish tone.
By the way, the vocals are by the voicebank IA, and this is one of the demo tracks unveiled before her official release.
Lost Time Memoryjin

Jin’s 15th work and the 10th Vocaloid number in the Kagerou Project.
This song plays a crucial role in the story and is also known for reaching a million views at the 8th fastest pace in history.
Its driving ensemble, featuring a hysteric guitar sound, seems to link with the impactful lyrics.
A rock tune where madness and pop sensibility coexist, it instantly pulls you in with its catchy chorus.
Lost Day Hourjin

A song that revisits the end of summer from an adult’s perspective within the story of the Kagerou Project.
Through lyrics that recall former friends amid everyday scenes and streets bathed in the glow of sunset, it reflects the contrast between the radiance of youth and life in the present.
The pastoral band sound really sinks in, too.
Included on the album Mekakucity Reload released in November 2018, it serves as an epilogue-like piece within a collection that arrived about five years and six months after the previous album, Mekakucity Records, carrying the lingering aftertaste and postscript of the story.

Artificial Enemyjin

The exhilarating, fast-paced guitar rock sound is thrilling and cool! Released in February 2011, this was Jin’s first work as a Vocaloid producer and the memorable first installment of the Kagerou Project.
It’s included on the album Mekakucity Days, and its arrangement—where intense band sound blends with digital noise—gives you the sensation of being pulled straight into the story’s world just by listening.
The lyrics, seemingly spoken from the perspective of an entity inside a computer screen to a “you” who’s turning your back on reality, are also striking.
Why not start by listening to this origin point?
At summer’s end I’ve forgottenjin

A nostalgic rock ballad that symbolizes the reboot of the Kagerou Project.
Featured toward the end of the third album, Mekakucity Reload, released in November 2018, this song is a poignant piece themed around fireworks at summer’s end and a parting of ways.
The wistful piano phrases and synth tones that seem to spread across the night sky create a fleeting beauty that draws you in.
The lyrics, in which the protagonist desperately wishes to keep holding hands until the very last moment, are heart-wrenching.
It’s a masterpiece that leaves you feeling the lingering afterglow of the series—impossible to listen to without tears.
Transparent Answerjin

Its fresh yet faintly heartrending band sound tightens your chest.
Depicting Shintaro and Ayano’s episode, “The Story of Avoidance,” this work is one of Jin’s signature numbers, included on the album Mekakucity Days released in August 2012.
A high-achieving boy and a girl who never stopped smiling—their missed connections and irreversible regrets are woven into a story that will move many listeners to tears.
It holds an important place within the series, with an alternate version also featured on the related anime album MEKAKUCITY M’s 2 for Mekakucity Actors.
When you want to reminisce about days gone by and sink into a sentimental mood, be sure to give it a listen.
Otsukimi Recitaljin

The Kagerou Project series has many cool songs, but this one is catchy, dazzling, and cute! Otukimi Recital, themed around Momo and Hibiya’s relationship, was released in 2013.
The energetic sound of the brass parts alone brightens your mood! And the lyrics, which convey Momo’s feelings as she tries to cheer up Hibiya, end up encouraging us, too.
When an unpleasant haze is swirling in your chest, this song might just blow it all away!
