TL;DR Review

Birdy the Mighty: Decode is a reboot of a sort for the original series. The OVA was adapted from the 1988 manga, while Decode is adapted from the 2003 manga. Kazuki Akane, the director for The Vision of Escaflowne, directed the Decode television series.

Birdy the Mighty: Decode takes on a much lighter tone than the OVA, especially in the art style. The animation is incredibly bright, to the point where any scenes in the day have a washout effect. The art is also a bit lazy as many none essential scenes lack any sort of detail, and the background is just a simple water paint backdrop.

The cheery opening theme “Sora (そら, Sky)” by Hearts Grow matches the new lighter theme of the series. The ending theme “Let’s Go Together” by Afromania is also uplifting and catchy.

More characters were introduced in the TV version with some tweak to the existing characters. For example, Natsumi Hayamiya, Tsutomu’s female friend and classmate. In the OVA she has a more prominent role and a love interest, while in the television show she is just a minor character. We also get to explore other worlds than just Earth.

Birdy the Mighty: Decode is an enjoyable anime, but its pacing is a little slow. The first arc is a bit boring and annoying as we mainly see our main character complaining a lot. This is a better than average anime and I recommend it to those that are fine with a slow-burn and chill anime to watch. This anime contains some graphic violence and mild suggestive themes/dialogs. Intended for young adults.

The Irregular at Magic High School Season 1 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.
