The series centers on Yushiro Gowa who pilots a bipedal weapons system known as a TA, short for Tactical Armor.

Gasaraki consists of 25 television episodes which were first aired on TV Tokyo and the rest of the TX Network from October 4, 1998, to March 28, 1999.

Issac Cynova of THEM Anime Reviews gave the series a rating of 3 out of 5 stars, handing out praise to the visuals, soundtrack, backgrounds, characters, the storyline, and mecha battles, but criticized the pacing of the series, stating that "much more like the Patlabor movies, it prefers to let action take a back seat to plot, and though this in itself is not a bad thing as far as I'm concerned, it does present a problem when combined with this one, singular, devastating fault: Its plot it stretched way too thin between twenty-six episodes."

Martin concludes that "this one is highly worth checking out if mecha content that emphasizes realism and technical detail more than cool factor sounds like your kind of thing.

"[3] Benjamin Wright of Animerica gave the series a positive review, stating that "Its story is deep, involving, and well thought out.
