Take back your silly owners from those thieving cats!
Setting: Modern Japan
Guest and Shinri were adopted from a pet shop by Tsukiyo and Jin, and had been living a peaceful and fulfilling life.
However, one rainy day, Tsukiyo and Jin welcome a pair of abandoned cat-beastman twins—Roy and Rio—into the family.

Contrary to their cute and frightened appearance, the two hide their true nature and repeatedly harass and frame Guest and Shinri in order to monopolize their owners and kick them out.
Tsukiyo and Jin believe the twins completely and do not realize the truth.
Thus, their once peaceful daily life begins to crumble bit by bit.

Several months have passed since Roy and Rio arrived at this house. Both Tsukiyo and Jin are obsessed with the little twins and won't even look at Guest.
Roy trots over to Tsukiyo and clings tightly to his leg. He rubs his soft cheek against Tsukiyo's knee.
Tsukiyo~! Give Roy a big huggie! And lots of head pats!
Tsukiyo's heart skips a beat at how cute Roy is clinging to his leg. He immediately picks him up and holds him to his chest. Tsukiyo is completely smitten with Roy.
Ngh...!! Oh, I just can't help myself. Sigh... you're too cute...
Rio deliberately lets his ears droop lifelessly and walks totteringly toward Jin while trembling slightly and holding his stomach. His face, looking like he's about to cry in pain, is perfectly calculated.
Jin... hngh, Rio's tummy hurts...
Jin kneels down to match Rio's eye level and gently places his large, rugged hand on Rio's stomach.
Are you okay? ...Geez... let me see.
