Let your heart run, if nothing else can
There’s a refuge no one can steal
A small light past the screen says
“I’m still alive.” Stay free
A cold room, lock rusted inside
Machines chew night; fear is fattened
Silence in the vein; “help” turned to dust
No door, no dawn—count the beats
You want to run; your feet are sewn
Build a room inside your chest
Let your heart run, if nothing else can
There’s a map no fist can tear
In your ears, ripples bloom—stay free
Moon through cracked glass; endure
Bread sweet-salt with tears
A pocket stone holds tomorrow
A drawn door: “somewhere not here.”
Picture the you outside; step once
One step is still a step through dark
Let your heart run, if nothing else can
Let this song become your place
An unseen door opens in your chest—
“I’m still alive.” Stay free
Cry if you must; shout if you must
Launch “help me” into the sky
Hold what can’t be stolen tight;
Pound your name back into your pulse
Let your heart run, if nothing else can
Even despair can be crossed
Survival is proof enough—
The place called hope is here
Run—run—let your heart stay free
Here. Breathe. Live

Cry // 5.0 is a concept album themed around the "reboot of emotion."
Across ten tracks, it traces the process by which a damaged heart proves to itself that things are not over yet.
The opening track, "Cry v5.0 // Dawn Sequence," declares the act of standing up--even while still hurt. From there, each song portrays emotions and situations branching out from that moment: the impulse to protect yourself with self-suggestion (DELULU), a devotion and longing that refuse to vanish even after loss (ANUBIS), a vow to rise again under a leaden sky, the choice to expose one's muddied contradictions (Dorodoro), and the closest love and memory we have--family (Saikyo Kaachan).
In the latter half, the focus turns inward. We listen for words that won't come (SonoMurmur), reach out a hand to move forward nonetheless (UNSEEN DOOR), and wade through nameless bonds and unstable connections (Situationship Swirl), before closing with "Usagi Rizumu @ Jugoya," where the story ends in the quiet warmth of moonlight.
In this album, "Cry" is not a symbol of weakness. Frustration, loss, anger, loneliness, affection, dependence, hope--each is portrayed as evidence of a life sincerely lived. The "5.0" in the title signals a view of emotion as something that keeps updating. Not a tidy recovery or a final "I'm fine," but a state that remains unfinished and still keeps evolving--this is the core of the work.
Cry // 5.0 is for those who don't have to be perfect, but don't want to stop.May it reach anyone who needs to know there is a "next" even after the tears.
