I think this is my absolute favorite by Katou Hayabusa. It still holds up to this day (just like most of his work). And it's not just a basic weight gain fetish manga, it fits the topic of this thread perfectly. I love the contrast between the flat and skinny look of her original form and how curvy, well-developed, feminine and fertile/mature she looks when fattened by the spell. In my "headcanon" the reason why the spell made her chubby everywhere instead of just making her boobs bigger isn't because she messed it up. I believe it worked as intended, and this is actually some sort of fertility spell in the first place which is supposed to do more than just breast expansion. I love how awkward and shy she initially feels about it, but later still opens up to Saito pretty quick. And I love how the ending reveals that Louise gradually gets chubbier permanently every time she uses the spell, but they still continue to use it which implies she eventually ends up looking like her transformed version permanently.
