The song "STRANGER" by MONDO GROSSO (featuring Asuka Saito) seems to be about the feeling of being lost and disconnected from reality. The lyrics convey a sense of confusion and disorientation, with the repeated phrases "さけび続ける" (screaming endlessly) and "こわれ続ける" (breaking continuously).

The protagonist seems to feel like a "stranger" in their own life, experiencing constant déjà vu and searching for meaning in a world that feels unfamiliar and uncertain. The lyrics "何処にいてもデジャヴ ストレンジャー羽織って" (no matter where I am, I wear the coat of a stranger) suggest a sense of alienation and detachment from others.

The song's various sections describe different scenarios and emotions: in the chorus, the protagonist feels like they are constantly spinning and breaking apart; in the B section, they imagine stopping the wind and suppressing the light; in the C section, they dream of being with someone forever in a box; and in the D section, they are enveloped in an eerie temperature and continue to be shown to themselves.

Overall, "STRANGER" appears to be a introspective exploration of the self and the struggle to find one's place in the world. The lyrics express a mix of despair and hope, with the protagonist searching for meaning even in moments of confusion and isolation.
