Plot Summary: In the distant future, a polluted world has been overtaken by havoc-wreaking creatures called Limbeekoon. Humanity, having been forced to relocate itself, must live in isolated mobile cities called Regios. A mysteriously skilled fighter named Leyfon Alseif enrolls in the Academy city of Zenri and is immediately noticed by Nina Antalk, leader or the 17 Military Arts Unit. He then reluctantly joins her squad, uncertain of what future awaits him and his new teammates within the city as well as the impending dangers in the midst of a plagued world.

The anime follows more or less to it’s light novel and manga counterpart. The opens with Leyfon Alseif and three others in his company battling a behemoth know as the Limbeekon (Flith Beast). During the middle, the flash back occurs to Nina Antalk looking for a new member to add to her mercarny team at school that will dissolve, because its short of members (4 total in a team). Soon entering, Leyfon meets Mifi Rotten who is a new student as well (Reporter) and as well as her senpai’s Narki Gerni and Meishen Trinden.

After the meting two students decide to fight causing a ruckus on campus. As the fight gets out of hand, Meishen is in danger of a collapsing building, but is saved by Leyfon. Minutes after the brawl, Leyfon meets the Student Council Presdient Karyan Ross who simply explains of how the Academy City is run by the students and he is overseer. He transfers Leyfon to the Military Branch that will help pay for his stay (which Leyfon as no choice) and Nina decides to take him into her group. After awhile Leyfon meets the girl who he thought heard of voice by telepathy to save Meishen. This girl later we learn is the brother to Karyan Ross (Leyfon doesn’t know).

After a few minor scenes (a laughable one at Meishen expense) the  scene stretches back to Leyfon and his team mates actually dispatching the beast they were fighting in a co-op offense of the three. In the last few slides as the opening theme plays and credits roll, the same girl in very beginning writes a letter that used as an Aside to explain to use the what is going on and as a Letter to Leyfon which ends the the episode.

Chrome Shelled Regios may not seem like the type of anime to change the genere it’s in, but it should be able to add one more series to anime library. From what I read from it’s counterpart, the manga does deviavate slightly and should add a more intresting direction and execution to plotline. I can’t say whether this series is a good one yet, but rest assured Chrome Shelled Regios has a lot more to show us in the future.
