Lifelight (Kagami Ochiai song)

Lifelight (命の灯火) is the theme song to Super Smash Keyboards 6, as well as Super Smash Bros. Ultimate and Super Smash Keyboards X. Hideki Sakamoto provided the song's instrumentals, while Kagami Ochiai sung the Japanese version of the song.

An abridged version of the song plays during the introductory sequence of the games the song appears in, while the full version plays during the end credits after finishing the game's campaign mode.

Music video
The official music video of the song is featured in the intro of Super Smash Keyboards 6. The game opens with James Rolfe pulling out his Zapper and commanding everyone to "not let a single one get away" and addressing the entirety of the game's cast at the edge of a cliff. The camera pans to reveal Death Mwauthzyx, who is accompanied by a series of Crimsonites. After Miyuki Takara, Leonard Slikk, and Rinnousuke Morichika comment on the anticipation of the upcoming battle, every Crimsonite that Mwauthzyx is controlling dissolves into him. Meanwhile, Hikari Uchida (in her spirit form) is seen praying as the bomb that will release his attack explodes.

After the bomb explodes, the music cues as the explosion creates an intense array of beams of light. Kagami Ochiai begins to sing the song as each of the victims is killed by the light.
