Poems of a Baseball FanaticHorie Kumiko

It’s a baseball anime with a very fresh concept: a female player as the protagonist.

It became a hit that gained widespread popularity, attracting not only male fans but female fans as well.

Perhaps it was around this time that women’s baseball began to draw attention.

Brave RaideenShimon Masato

A boys’ dream: a hero-themed anime.

The opening theme is march-like, a very impactful song I can still sing from the beginning even now.

The climactic scene where the protagonist enters the combat robot is especially memorable, and it reminds me how excited I always felt.

Gundam is an eternally charismatic anime that continues to evolve even today.

As for the theme song of the original Gundam, I bet everyone can sing the full chorus, right? Gundam might be the only series where people can sing both the opening and the ending songs.

I am Teppei.Fujimoto Fusako

A smash-hit anime by Tetsuya Chiba.

Among the many sports anime, there aren’t many set in a kendo club, so I imagine it left a strong impression on a lot of people.

The very cheerful characters are loved by everyone, and the theme song is energetic, making it easy to warm up to.

(BD) Ranma 1/2 OP 'Don't Make Me a Spoiled Brat'
Ranma 1/2nishio etsuko

One of Rumiko Takahashi’s representative anime works, Ranma 1/2.

The protagonist has the bizarre trait of turning into a girl when he comes into contact with water, which is really amusing, and his father comically turns into a panda.

The protagonist’s female form is very cute and perfectly matches this theme song.

It’s sure to get you pumped if you sing it at karaoke.
