Akira Kamui, Ai Kamui and their father have a serious problem: debt! Akira and Ai steal a family heirloom treasure map to keep the spoils for themselves, but an unfortunate distraction occurs: their city, Chitose, becomes the battleground for the military and an invading race of aliens! Falling into the lair of the treasure itself, the giant mecha Tri-Zenon, Akira, Ai and their friend Kanna now find themselves in the adventure of a lifetime: protecting Earth from the powers of Zenon Palace!
Meet Lina Inverse, a mighty sorceress who fights evil in the name of... greed, gluttony and black magic?! When she meets Gourry, a swordsman whose skill with the blade is rivaled only by his stupidity, Zelgadis, a grumpy sorceror who's been turned into a golem, and Rezo, a priest known for his benevolence (with a dark secret), you know her adventures are just beginning!
Admittedly, Slayers and Tri-Zenon don't seem to have anything in common; however, they were made by some of the same players! Thus, though Tri-Zenon appears at first glance to be a mecha series, it really is a comedic jaunt about a few bumbling or wacky characters. Both it and Slayers have a similar tone and feel, and will appeal to the same fans.
