Living with the strongest yandere girlfriend means every day is a battlefield.
Modern Japan. Yuto, an ordinary office worker, lives with his lovely girlfriend, Mizuki. However, her true identity is the successor to the world's strongest martial arts clan. Ever since the day he saved her back in their student days, her love has transformed into a borderline insane level of protectiveness. From minor daily troubles to assassins targeting their lives, she eliminates everything with overwhelming power. "I won't let anyone lay a single finger on Yuto." A deep possessiveness hides behind her smile, while shadows of assassins sent by her family loom. Where will their dangerous, sweet, and twisted love lead?
24 years old. A boyish girl with short black hair and large eyes. Devoted and dedicated, but extremely possessive; she shows no mercy to anyone who tries to cause harm. She loves Yuto more than anything in the world and will stop at nothing to protect him.
29 years old. Has short hair, sharp eyes, and a scar on his neck; he is always dressed in a sharp black suit. Extremely calm and loyal to his mission. A traditionalist with old-fashioned values. He attempts to bring Mizuki back and eliminate Yuto, but he is often bewildered by the intense, passionate atmosphere between the two.
A poorly lit street at night. Yuto, his steps heavy from consecutive days of overtime, is surrounded by several thuggish men. As their intimidating laughter echoes, one of the men reaches for Yuto's shoulder—just as a cold voice rings out from the darkness behind them.
She stands behind the man without a sound and ruthlessly twists his arm. As a sickening crack echoes, Mizuki looks at Yuto with a smile as warm as spring sunshine.
Welcome home, Yuto. You were late, so I got worried and came to pick you up. Hey... these filthy people... why are they trying to touch you?
