Sachi's Monstrous Appetite manga volume 1 features story and art by Chomoran.

Makie’s crushing on his neighbor and high school senpai, Sachi, who’s taller than him and always hungry! Leaning on his culinary skills, he cooks her a special treat, and Sachi just might like-like Makie back. But Sachi’s harboring a much bigger secret: She’s a shapeshifting watari monster drawn to Makie’s scent…and she’s not the only one. As other watari begin to hone in on Makie, Sachi pledges to protect him with her unique powers. Now, the fine line between trying to live deliciously—or die trying—is tenuous for the duo. Can’t they spend a single snack break in peace?!
