Description
The Hyper Gyanko is a custom Gunpla constructed by Tateo Sazaki. Its design merges the likeness of Tateo's older sister, Kaoruko Sazaki, with the YMS-15 Gyan mobile suit, adopting an "MS Girl" aesthetic.

The unit wields a pair of high-output beam sabers specialized for piercing and stabbing attacks. Its primary armaments are a pair of missile shields, gifted by Tateo's elder brother, Susumu Sazaki. Mounted on the Gunpla's back via flexible arms, these shields move independently, a design inspired by the AMX-104GG R-Gyagya used by Kaoruko Sazaki.

The missile shields possess extensive offensive capabilities. They are equipped with stored needle missiles, used to restrain enemy movement or for intimidation, though massed volleys can be lethal. The shields also contain hide bombs, a type of space mine that floats freely to damage nearby enemy units. A beam blade emitter is located in the center of each shield.

This Gunpla appears in a narrative personified as a warrior named Hyper Gyanko. Alongside a personified Winning Gundam named Super Fumina, they undertake a quest as warriors of justice. They investigate the abduction of Beargguys from a Petit’GGuy village,追踪 the culprits to a beach where the Beargguys are found hanging on racks. They are attacked by UFO-like objects revealed to be Acguy heads, which hold a grudge for not being used in Gunpla construction. After being overwhelmed and having their armor destroyed, the characters are re-energized by the village inhabitants. The conflict resolves when the Acguy heads are sent to a Gunpla factory to be reborn as new parts.

The model kit's design incorporates special materials in the chest and leg joints for natural and organic posing. The kit includes two facial expressions, clear eye parts, accurately reproduced twin tails, two shields, two beam sabers, and a display base.
