- Chest (チェスト)
- Shuuji-kun (修二君)
- Kirikirimai ~DISCO MIX~ (キリキリマイ)
- Chest ~LIVE MIX featuring PAUL GILBERT~ (チェスト)
- The PV for "Chest" was recorded at a hotel; the song itself is short because the band said "Performing violent songs is very tiring." Violent songs with short durations would reflect in later songs such as "INSANE" (world world world).
- The original title of "Chest" was "BUSTERS", but because Orange Range's members were "addicted to Karate Baka Ichidai", they changed the name to "Chest" as a sort of shout-out.
- In the PV for "Chest", the standing positions for Yamato and Hiroki as well as Yoh and Naoto are switched from the usual.
- Some report that you can faintly hear "Kirikirimai Kirikirimai" in "Chest", and sometimes the faint lyrics are displayed at in the Karaoke version.
- "Shuuji-kun" is a solo done by Hiroki but composed by "Naoto-rin" (this is after he made the group "Soy Sauce", which would be featured in later OR songs). The song seems to tell how Shuuji-kun goes to a first joint party and meets a girl who is not "his calendar age" (the interpretation of this song is rather vague and is most likely incorrect due to lack of English translations of the song).
- "Chest" was included in the album The songs for DEATH NOTE the movie ~the Last name TRIBUTE~.
