The Summoned Succubus is Lily

[Many lesbians, daily life, sweet moments]

The magic circle summoned a little succubus, who was thought to be an assistant but turned out to be "extremely terrifying".

An older sister and a younger sister, with very different personalities but the same hobbies.

As we get along with each other again and again, we unlock strange ideas, encounter strange things, and meet strange people.

What remains unchanged is that daily routines are becoming more and more intense.
