On the first page, we see that Nemu is four levels higher than Mahiro. This is proof that Mahiro turning into a girl is a complete detriment to his health. He just doesn't have enough time to dedicate 100% of his time to grinding in an MMO and literally nothing else. Absolutely heartbreaking. (Thankfully, though, Nemu is still healthy.)
Anyways, this was a good chapter. A lot of the recent ones have been more gag-focused, so I liked that this was more character-based. Felt like a bit of a return to form.
