Me and the Alien Mumu Vol.1

by Hiroki Miyashita

Planet Earth has been invaded! By a cat-shaped alien obsessed with...appliances, no less. An alien named Mumu is a survivor of a civil war that saw the destruction of his planet's scientists, leaving only its fools alive. In an attempt to understand the advanced technology his species left behind, he's infiltrated Earth, a planet with a lower level of civilization, to study their so-called "home appliances," which contain facets of all kinds of technological knowledge. So begins the adventures of Sakurako, a university freshman and Mumu's new and unexpected accomplice, as she navigates a wild and exciting campus life.

So, this is a series for someone—not me, but someone. Probably.

I found this first volume to be very haphazard and disjointed.

The character introductions are rushed and the exposition is very “blink and you’ll miss it”. Like, I don’t feel like I understand these characters and their circumstances enough to relate to or emphasize with what’s going on in the story—which makes for an odd, removed reading experience.

More than anything, this feels like a manga adaptation of a “how to use” guide for the many products and technologies spotlighted between chapters. Which, again, is just kind of odd.

Somehow the cat-like alien in this story is the least disorienting piece. We just don’t spend enough time with them in this first volume to appreciate them though.

Anyway.

I don’t feel like the intended audience for this series—but, I don’t necessarily think that means this is bad~

this one was so strange. i read the other reviews where i was informed this was a bit strange but i don't think anything could really prepare me for how strange. i've definitely read/seen/experienced things that are stranger, but this just didn't cohere for me. the tonal shifts were too vast and i can't say i appreciated how the women were written in this.

i liked the informational/educational bits, there were generally interesting and helpful facts. that was probably the best part.

Definitely want read more of this series. There are definitely laugh out loud moments. Plus it is educational with the explanations that they have between each chapter.

I like cute animals and I like learning about niche topics. So a story about an alien cat who seeks to understand household appliance engineering is a weird but welcome read

Edit: this book helped me fix my fridge +1 star

I like the concept and it is a fun way to learn more about appliances. However when reading this you can definitely tell that it was written by a man (in a bad way).

A fun idea that has lots of great info and beautiful, easy to understand, diagrams of many mechanical devices. The plot is really more edutainment with some hijinks thrown in, but the presentation and theme is solid. A very easy 10 pages at a time kind of read as opposed to a super binge. Lots of "I did not realize that!" moments and great tips too for the casual DIY repair student.

I also appreciate the fact that despite all expectations the manga never devolves into constant catch phrases or KAwAiiii! statements.

Enjoyed!

Interesting and educational. The alien cat Mumu has come to Earth to try and figure out how to save his own planet. Currently, that means learning how different appliances work/are built. Between chapters, readers will find legit scientific information.

I can't stop myself from thinking of this as "Bill Nat the Science Cat."

I was not prepared for all the learning.

Weird! Educational! Fun! But only loosely tied together with plot
