Shin Ultraman

In both shows the leads are socially awkward outcasts. They also idolize their popular love interest.

New Ultraman, Shinji Kaminaga, a man who could transform into a building-sized hero when various creatures threatened his city.

First impressions, the humor and team makeup of BLAZAR remind me of Shin Ultraman.

Maybe it's because they both take heavy inspiration from Showa Era Ultraman.
I've only seen ULTRASEVEN (watching it in tandem with Blazar's broadcast) but the episodes that range from goofy to scifi thriller with that ever looming threat of Kaiju felt similar.

The universe is not just one. Within the overlapping layers of the multiverse, there exists another Earth that looks exactly like Earth. In "MultiEarth ?0073", which has entered an era of cosmic coexistence, crimes involving the exploitation of energy-based lifeforms known as "Emorgy" are breaking out one after another. Reiji Doki, an investigator for the Galaxy Federal Police, is Gavan Infinity, the only person in the universe permitted to claim the title of "Space Sheriff Gavan". However, he is stationed in the backwater Archives Department. His true objective is to investigate Emorgy crimes across dimensions. Chasing these inter-dimensional threats, Reiji leaps through space-time, encountering the Gavans of various dimensions and joining forces to bring justice to the multiverse. "Jo-Chaku!" The Space Sheriffs Gavan transcend the boundaries of the universe to strike down evil!
