TL;DR Review

Diebuster is like a spunkier younger sister of Gunbuster. They are related but have their own different personalities. Diebuster feels like Gainax took what they’ve learned from making FLCL then applied it toward the Gunbuster universe.

The art and tones of Diebuster and Gunbuster are very different. If you didn’t know better, you may not even think they are related. Diebuster is more light-hearted than the original, and some may feel it’s too quirky. The world of Diebuster is vibrant.

The music of Diebuster is great, with the opening and ending theme especially catchy. You can tell the tone of the anime just from the song “Groovin’ Magic” by ROUND TABLE feat. Nino.

Despite a big cast, there were only a few memorable characters in Diebuster.

I highly recommend Diebuster, especially if you like FLCL and want more of that type of anime. I still think Gunbuster is the better OVA, but Diebuster is still an incredibly good OVA to watch. The OVA contains graphic violence.

Macross Plus OVA Series (1994) Review

Macross Plus is a four-episode anime OVA and a theatrical movie.

The year is 2040 and the galaxy is flourishing with several colonies and advanced technology. AI is near perfection and the current top idol is the near-completed Virturoid Idol Sharon Apple. All that is missing are her actual feelings, which instead are supplied by Myung Fang Lone. Sharon’s debut concert is on planet Eden, where at the same time, fighter pilots Isamu Dyson and Guld Bowman battle over air superiority for the Supernova Project. Isamu, Guld and Myung were once childhood friends, but after an accident seven years ago, they went their own separate ways. With Myung back in the picture, the old disputes are once again awakened. And when an unstable and illegal AI technique is installed in Sharon, the situation is worsened.

One-Punch Man Season 1 (2015) Review

The story takes place in the fictional metropolis of City Z, Japan. The world is full of strange monsters that mysteriously appear and cause many disasters. Saitama is a super powerful hero who easily defeats the monsters and other villains with one punch. However, after becoming too strong, Saitama has become bored with his powers and is always trying to find stronger opponents who can fight him.

On his adventures, he meets new friends, enemies, and his own disciple, the cyborg Genos, and also joins the Hero Association in order to gain fame for all of his actions to prevent evil. Despite defeating many strong monsters that even the Hero Association’s top heroes are unable to defeat, Saitama struggles to gain respect. Most people discriminate him due to his plain physical appearance and some accuse him of being a counterfeit hero. Only a small number of individuals recognize his incredible talent and humility towards others.
