Overview
アノーイング！さんさんウィーク！ (Annoying! Sun Sun Week!) is the opening theme of the television anime 先輩がうざい後輩の話 (My Senpai Is Annoying), a workplace romantic comedy that aired in 2021. The song was composed, arranged, and written by Junky, a producer well known in the Vocaloid and doujin music scenes for his upbeat, melody-driven pop tracks. The vocal performance is split among four of the anime's main voice actresses: Tomori Kusunoki (as Futaba Igarashi), Saori Hayami (as Touko Sakurai), Reina Aoyama (as Natsumi Kurobe), and Aoi Koga (as Mona Tsukishiro), each bringing their character's distinct personality to the chorus.
The track joined the maimai DX song list as part of the FESTiVAL edition, released on September 15, 2022. Clocking in at a brisk in-game length of 1:28 with a steady 140 BPM, the song was arranged into four DX-format charts. The Expert chart was designed by はっぴー, while the Master chart, pegged at level 12+ with a constant of 12.8, was crafted by ロシェ@ペンギン. The song was later removed from the arcade lineup on August 22, 2025, making it a time-limited entry in the series.
