I've completed my collection of Hyaku Shiki Kai variations in HG (High Grade) kits.

Hyaku Shiki Kai Style
The "MSR-100S Hyaku Shiki Kai" is a mobile suit that appeared in the B-CLUB project "Z-MSV" in 1985, during the broadcast of the anime "Mobile Suit Zeta Gundam." The design is by Kazuki Fujita. As the name suggests, it's an improved version of the Hyaku Shiki.

This was built in April 2025, based on the HG Revive Hyaku Shiki.
