TL;DR Review

I had expected this to be a throwaway filler episode but was surprised it was actually impactful.

The animation is on par with the first season of Birdy the Mighty Decode.

The opening theme is “Kiseki (奇跡,Miracle)” by Nirgilis, the same awesome song as season two. We are, however, treated to the ending song sang by Birdy herself with “Bye Bye” (バイ バイ) by Chiba Saeko.

The OVA covers how Sayaka life is like in Kobe, a little bit on what happened to Capella, and other subplots that tied the first and second season together nicely. Though this OVA was released after season two of Birdy, you can watch this first.

I recommend this OVA for the fan of Birdy the Mighty Decode. This anime contains some graphic violence and mild suggestive themes/dialogs. Intended for young adults.

The Irregular at Magic High School Season 1 (2014) Review

The series is set in a world with an alternate history, where magic exists and has been polished through modern technology. However, the ability to use magic is determined by genetics, limiting the number of magicians in existence. Following the Third World War, the world’s superpowers shifted to these four nations: The United States of North America (USNA), New Soviet Union, the Great Asian Alliance, and Japan. In Japan, the magic community is informally governed by the ten master clans in lieu of the government. Due to the limited number of magicians, they are treated as a commodity and are forced to enter magic related schools and professions. Nine magic high schools exist in Japan; they each specialize in different aspects of magic and are simply referred to by their numbers.

The story follows Tatsuya Shiba, a bodyguard to his sister Miyuki Shiba who is also a candidate to succeed in the leadership of the Yotsuba clan, one of the Ten Master Clans that govern Japan’s magicians. They enroll at First High School which segregates its students based on their magical abilities. Miyuki is enrolled as a first-course student and is viewed as one of the best students, while Tatsuya is in the second course and considered to be magically inept. However, Tatsuya’s technical knowledge, combat abilities, and unique magic techniques cause people to view him as irregular to the school’s standardized rankings.
