The Testament of Sister New Devil

Romance · Fantasy · Action

Basara's new stepsisters bring demon politics into his home, framing supernatural combat around a deliberately explicit harem setup that is central to the series rather than incidental decoration.

Synopsis
The Anime Lad

Basara expects a new blended family when his father introduces Mio and Maria as his stepsisters. The arrangement soon acquires supernatural danger and a binding contract whose terms are spectacularly unsuitable for household discussion. Combat sits beside highly explicit fan service from the start. Prospective viewers are given enough evidence to make an informed decision very quickly.

Super Eyepatch Fox

Basara's new stepsisters are tied to the demon world, and his own family history is hardly ordinary. A magical contract complicates their attempt to share a home while hostile forces close in. The series combines fantasy combat with persistent explicit fan service, making its intended audience and mature-content warning clear almost immediately.

Gigguku

There is no pretending this is coy. Basara gets two supernatural stepsisters, then the household situation detonates as the show charges into demon conflict with fan service at MAXIMUM intensity! Underneath that, the setup does have a protective-family impulse and a magical contract that keeps everyone uncomfortably connected. Still, the explicit material is the dominant flavor, so know exactly what kind of midnight snack you are ordering.

Father's Basement

The supernatural family premise might support a decent action romance, but explicit harem mechanics keep elbowing that story out of frame. Basara's new home links him to Mio and Maria, whose identities bring magical threats and binding complications. The combat is energetic enough. It is simply not the main reason the production expects its audience to attend, a priority established so early that nobody can claim false advertising.
