Nadeko from the Monogatari series wrote and illustrated a manga. It's an integral aspect to her character in Koimonogatari. I was going to do that joke where I roleplay as Kaiki, but someone beat me to it. So, I guess I'll just review this for real.

The art is really cute. It's kinda scratchy, but not chicken-scratchy. It's got this sketchbook-like feel; the sorta thing a middle schooler might turn out if they were trying to make a manga, but more polished. There are also a number of colour pages, and it's coloured well, too! Clearly the mangaka put a lot of effort into drawing this right, while also maintaining the meta feeling of being able to imagine this as something Nadeko drew.

The story is, as you might expect, something a middle schooler might turn out if they were trying to make a manga. It's filled with clichés, the story is kind of nonsensical but also engaging, and it's very wish fulfilment-esque, but not in a bad way. Yes, you can see everything coming a mile away, but it's cute the way it's done. This is just a bunch of cute fanservice. Cute, cute, cute.

There is nothing of particular substance here. Tsukihi makes a cameo. Things just sort of happen. A lot. And then they stop happening. Without warning.
