Sun promotion entertainment

Sun promotion entertainment (サンプロモーションエンターテイメント San puromōshon entāteinmento), or SUNPRO (サンプロ SANPURO) for short, is the entertainment agency that manages the units of ZIX, TOBARI, & SAUDADE.

About
Unlike TSUKINO, most of SUNPRO's agency information has not been made publicly available yet, including their office location, president's name, nor date of formation.

It is said, however, that as an agency they're roughly the same size as TSUKINO, and that their president went on hiatus for a while but recently returned. Their president is apparently a good person with a keen eye for new talent, having personally scouted Growth's Koki Eto when he was first starting as an idol.

Overview
Sun promotion entertainment is a fictional 2.5D entertainment agency handled by movic. They are the in-universe rival agency of TSUKINO TALENT PRODUCTION, but in reality their releases and unit management is handled by the same company as TSUKINOs units.

When first introduced, the company was only responsible for one unit, ZIX; the rivals of Growth from TSUKINOs ALIVE series. It was later revealed that the original three members of Growth were formerly managed by SUNPRO at some point in the past, before they auditioned for TSUKINO in 2015.

The company later expanded its work to include the newer unit, TOBARI, in 2019. TOBARI are part of the X Lied Project, an inter-agency project between SUNPRO and TSUKINO featuring TOBARI and TSUKINOs unit, infinit0. This project was further enhanced in 2020 with the formation of pioniX, a mix-unit formed by joining TOBARI & infinit0 that is jointly handled by SUNPRO & TSUKINO.

Another unit managed by SUNPRO, SAUDADE, was introduced in pioniX's SEASONS series with the introduction of a new character from said unit. So far not much is currently known about SAUDADE, including how many members are in the unit nor what kind of music they produce.

As of 2022, SUNPROs units now feature releases of unit CDs, drama CDs, & online drama series, as well as appearances in several anime series, stage play series, & a manga appearance.
