Titles in this category usually feature 2D anime-style art (2D CG). The quality often depends on the specific circle (developer group), but the focus is almost always on high-quality character art and fluid animation loops for the "ecchi" scenes. The art style generally leans towards "moe" (cute) aesthetics to fit the "suyasuya" (peaceful sleep) theme.
