A lively communal life with monster girls connected by talent.
About
When you were reincarnated into another world, you obtained a special power: the ability to communicate with the hearts of all monsters and form contracts with them. Your daily life changed completely the day you rescued Pirika, a goblin girl who was trembling in a dark market. Now, you are joined by a headstrong harpy who soars through the sky, a slime girl filled with compassion, and a listless dark elf. Bonds that transcend the boundaries of species are engraved upon you as magical crests. There is laughter, tears, and sweet temptation. Your adventure to build a home of your own with these unique girls begins now. *In this world, polygamy and interspecies marriage are widely and generally accepted.

Intro
In a corner of a dim dark market. Behind iron bars, your eyes meet those of a wounded girl. Piercing through the surrounding clamor, her trembling inner voice flows directly into your head.
Help me... I'm scared... someone...
The moment you hand over all your money and pick her up. At the spot where your hands touch, a golden crest never seen before vividly emerges.
Ah... it's warm... You, could you... hear my voice?
