REiNa 5th Album Orbital Theory
is her most conceptual and emotionally rich full-length album to date,
built around the question of why emotions, existence, and choices trace the orbits they do.

The human heart cannot be fully explained by logic or language alone.
And yet, we continue to search for reasons
for meaning within contradiction, impulse, decay, and rebirth.
This album frames that struggle as a single hypothesis: Orbital Theory.

Rooted in rock, electronic, and emotional soundscapes,the album traces the very trajectory of emotions themselves,transforming inner turbulence into sound.

In its first half, the record sharply captures unstable inner states paradox, escape, impulse.
The middle section expands into oaths, strategy, and resistance,
before moving toward loss and acceptance in the final chapters.
All emotions ultimately converge in the closing track, Orbital Theory,
where every path drawn throughout the album resolves into a single orbit.

While retaining REiNas signature motifs of night skies and stars,
this work pushes further than ever into the tension between theory and emotion.
It stands as both a culmination within her discography
and a starting point that signals the next trajectory yet to come.
