The word Infinity obviously connects to Reiji’s version of Gavan, but its deeper meaning remains a fascinating mystery. Does it simply describe his ability to travel through countless universes, or does it refer to a specific power or cosmic principle? The final television episode itself is titled “Infinity,” which makes the term especially significant.

It could also describe the fundamental nature of the Gavan system. If there can be multiple Gavans across different realities, perhaps “Infinity” represents the idea that the Gavan identity is not limited to one universe. Reiji’s title could therefore symbolize the connection between all of these versions rather than merely being the name of one armor.
