Yakusoku no Kizuna

"Yakusoku no Kizuna" (約束の絆, lit., "Bonds of Promise") is an insert song introduced in episode 6 of the Kyoukai no Kanata anime series, "Shocking Pink". It was performed by Risa Taneda, Minori Chihara and Yuri Yamaoka, playing the roles of Mirai Kuriyama, Mitsuki Nase and Ai Shindou respectively.

It is included on the Kyoukai no Kanata Original Soundtrack "Beyond the Melodies".

Background
In the anime series, the song was supposed to be the trump card against a particular fruit-type "youmu" (lit. Dream Catcher) whose weakness is the presence of cute girls and dance and song. According to Hiroomi Nase, it was the same song used in the most recent encounter with this youmu, and was successful in taking the youmu's attention enough for someone to eliminate the creature.

The song's lyrics contain inspirational messages related to friendship and facing the hardships of life, accompanied with a combination of guitars, electronic music and percussion common to Japanese pop music.
