Here are the lyrics for the ending theme.

Given the prevalence of Attack on Titan (Shingeki no Kyojin), misheard lyrics are extremely common. The phrase “shinseki no ko” sounds like (進撃の巨人) spoken quickly. And “o tomari dakara de na” sounds like “otoma ni dakarete na” – which appears in no song.

The chorus, "[Chorus lyrics]," highlights the theme of self-discovery, with the protagonist grappling with their identity and purpose. The use of metaphor and imagery adds depth to the lyrics, inviting listeners to interpret the message in their own way.

The title itself suggests a theme of connection or unity between two people, much like stars that are grouped together in a constellation.
