Overview
Rei Rei (レーイレーイ) is a high-energy electronic track by composer Kairiki Bear (かいりきベア) featuring vocals by Matsushita (松下), originally introduced in CHUNITHM CRYSTAL and later ported to maimai DX Splash on November 27, 2020. The song arrived as part of the cross-title collaboration linking maimai, CHUNITHM, and ONGEKI, a shared ecosystem that regularly moves tracks between the three Sega rhythm games. During the Splash version, players could unlock Rei Rei through the Kairiki Bear Area event at the 196km milestone. The jacket artwork depicts Shishido Misuzu (宍戸 美鈴), a CHUNITHM character making her companion-character debut across to maimai through this port. At 188 BPM, the track delivers the brisk, synth-driven sound Kairiki Bear is known for, with Matsushita's vocals carrying an energetic, slightly playful delivery. The song's chart lineup underwent notable revision over time: the Master chart originally debuted at level 12+ and was promoted to level 13 starting with the BUDDiES version, while the Re:Master chart, added on November 24, 2023, totals exactly 999 notes, one short of a clean thousand, a distinctive count for its 13+ difficulty tier.

Trivia
- Rei Rei was originally featured in CHUNITHM CRYSTAL before being ported to maimai DX Splash, part of the ongoing cross-title song exchange between Sega's three rhythm game franchises: maimai, CHUNITHM, and ONGEKI.
- The jacket artwork features Shishido Misuzu (宍戸 美鈴), a character from the CHUNITHM series. She was the first CHUNITHM-original companion character (つあメン) to be brought into maimai through a collaboration port.
- The song was obtainable through the Kairiki Bear Area (かいりきベアちほー) in Splash, unlocked at the 196 km travel milestone.
- Two in-game titles are associated with this song: 'マ？マ？マ？マ？' (earned by playing the song on Maxi/Standard difficulty in a single credit) and '「……そろそろお別れみたい」' (earned by achieving FULL SYNC DX on the Master chart). The second title translates to '...It seems it's about time to say goodbye.'
- The Master chart was originally rated level 12+ from Splash through FESTiVAL+, then upgraded to level 13 beginning with BUDDiES, a relatively uncommon level revision upward.
- The Re:Master chart, added nearly three years after the song's initial release (November 24, 2023), totals exactly 999 notes, one note short of 1,000, making it the highest-note-count chart for the song despite being a 13+ difficulty.
- Each of the three hardest charts was designed by a different notes designer: Expert by 華火職人, Master by シチミヘルツ, and Re:Master by Luxizhel.
