Overview
The Kerberos saga manga sidestories were unveiled in Monthly Comic Ryu vol.1, issued in September 2006. The Kerberos and Tachiguishi joint universe first appeared in While Waiting For The Red Spectacles, the 1987 radio drama that launched the Kerberos saga.
Two independent arcs based on these character groups were created with shared reference and characters such as Moongaze Ginji featured in The Red Spectacles live action movie. Later, the "old time gone of tachigui" is referred by Hayashi in the movie's 1991 sequel StrayDog. Jin-Roh, the last episode of the feature trilogy, features a scene referring to the January 1st, 1960 Zengakuren-Bund joint communist militants and sympathisans protest in front of the National Diet Building. The same scene is portrayed in the prologue of Kerberos Panzer Cop vol.1s 1999 renewed edition, and is referred in Tachiguishi-retsudens Foxy Croquette O-Gin chapter.
