Tiny Homunculus.

Notes:

Normally, I would post something like this in the Anime/Manga gallery. But her face was too pure that it felt like it needed to be here.

Hakase no Kimagure Homunculus is a slice of life/sci-fi/comedy manga. The focus is on the smol homunculus, Ryuuchin, and her training to be a sort of 'healing fairy' for the populace. But she acts more like an animal and her gag is literally biting the hand that feeds her. It's cute but the series will go stale if the biting continues in later chapters.
