The Astray Red Frame Kai is the upgraded version of the MBF-P02 Gundam Astray Red Frame developed and piloted by Lowe Guele. It first appeared in the photo series Mobile Suit Gundam SEED VS Astray.

An upgraded form of MBF-P02 Astray Red Frame developed by Lowe after his first encounter with LN-GAT-X207 Nebula Blitzs, the major change to the suit is the replacement of the Red Frame's backpack with Tactical Arms IIL and its mount. Besides the two head-mounted "Igelstellung" 75mm multi-barrel CIWS, Tactical Arms IIL and "Gerbera Straight" katana, Red Frame Kai is also equipped with "Tiger Pierce" Katana. It no longer uses the physical shield and the beam torch component of Tactical Arms IIL replaces the Type 71 beam rifle.

Like MBF-P03R Gundam Astray Blue Frame 2nd Revise's Tactical Arms II, Tactical Arms IIL can also transform into multiple forms, with each form granting Red Frame Kai unique abilities. Compared to Blue Frame 2nd R's Tactical Arms II, Tactical Arms IIL only retains the Sword form and a slightly altered Flight form. The other 4 forms, Arrow form, Work form, V form, and Delta form are new.

Other than these different forms, Tactical Arms IIL can also function as a "Maga no Ikutachi" Energy Absorption Claw and as a DRAGOON. The beam torch component can be detached and used as a welding tool or a beam rifle by adjusting its output. Tactical Arms IIL is a product of all Lowe's knowledge however its multiple forms and functions also increase the chance of it malfunctioning and make its maintenance difficult.
