This is simply outstanding in every single way a manga can be.

Kei Yonagi is a really compelling main character, she's fun, she has a real character deveolpment throughout the series.

The secondary characters are amazing as well, with some clever and really smart writing and breathtaking visuals by the 22 year old mangaka drawing it and the author.

Don't think this is just a mere story about "becoming an actress", Act-Age is a story about many things. Dealing with loss, death, sadness, overcoming your personal problems to do something greater.

The first 20 chapters or so are really slow, but after the first arc (Death Island) ends, the story goes on full wild. Galactic Railroad has some philosophical content that really made me feel something. It reminded me of seinen mangas like Oyasumi Punpun and Vagabond. Yeah, the writing in this manga is really THIS good.

In my opinion, this is the best Weekly Shounen Jump has to offer as of right now.

Go read it! Now! You'll have a good time! This isn't a silly story about a little girl trying to become an actress. Trust me. Kei Yonagi is maybe the greatest woman main character to ever come out of a shounen manga. She's even better than Jojo's Bizarre Adventures Stone Ocean's Jolyne Cujoh. She has a proper character grow. In fact, almost every character in this manga has a proper character arc.

Read it!
