Episode 102:
The Pretty Face Who Hunted a Rich Husband for a Life Reversal

"I'm sorry, I seem to have lost my key." The technician opened the door without suspicion, and she brazenly walked right into the apartment. Rummaging through the balcony, she found an 8-inch knife.

So, who exactly was this uninvited guest?

From a young age, Mai Takahashi's stunning looks always put her in the spotlight, and people's favors came to her for free. In college she dreamed of becoming a model, and after graduating she took a standard corporate job like everyone else — but found the ordinary desk work unbearable, both stifling and underpaid compared to the life she imagined for herself.

A New Career Path: Marrying Rich

Mai eventually turned to her looks, working nights at an exclusive club where the clientele spent staggering sums without hesitation. Immersed in that world of casual luxury, ordinary work started to feel pointless to her — grinding for a modest paycheck seemed, in her eyes, simply inefficient compared to finding a wealthy man to support her. Marrying rich became, quite literally, the career path she chose, and she began a methodical search for the right target.

In December 2019, she found him: Tsukasa Shirai, an elite tax accountant with a six-figure salary, stable career, and real social standing. They met at the club where she worked, and Mai approached the relationship with total strategy — researching exactly what he wanted in a woman and shaping herself to fit it. It worked: within six months, they were living together in his luxury apartment.

A Suffocating Obsession

Living together revealed the gap between them — Mai was already envisioning marriage, while Tsukasa wasn't taking the relationship nearly as seriously. Sensing her plan slipping away, Mai's anxiety curdled into obsessive control: tracking his whereabouts, checking his phone, even calling driving ranges directly to confirm he was actually there when he said he'd be. In privacy-conscious Japan, this level of surveillance was especially suffocating for Tsukasa, and despite his repeated requests that she simply trust him, the conflict only deepened. Two months into living together, a familiar fight sent Mai storming out for good — or so it seemed.

Once the anger faded, Mai recalculated: no other prospect matched Tsukasa's value, and losing him would waste everything she'd invested. She won him back through relentless effort and appeasement — but this time, Tsukasa insisted they not live together again, wary of her possessiveness. The reconciliation didn't last. Mai's controlling behavior resurfaced, and Tsukasa, unable to bring himself to end things outright, began openly seeing other women instead, seemingly hoping she would be the one to walk away. It only intensified her obsession. On October 26, 2020, less than a year after they met, Tsukasa finally ended it for good — taking back his spare key and blocking her number, determined this time to make it stick.

The Locksmith

Mai wasn't ready to accept it. Two days later, on the afternoon of October 28, while Tsukasa was out drinking with friends, she made her way to his apartment. When he finally returned home in the early morning, he froze — Mai was sitting on his living room sofa, waiting. She begged him to reconsider, expecting the same outcome as before. This time, Tsukasa held firm, telling her it was over for good and ordering her out immediately.

It was only once police pressed her that the truth of how she'd gotten inside came out. After Tsukasa cut her off entirely, Mai's anger curdled into something far darker — convinced that "if I can't have him, no one can." Rather than force her way in, she calmly called a locksmith, claiming she was locked out of her own home; neighbors, aware she and Tsukasa had lived together, assumed she was simply patching things up with him and thought nothing of it. Once inside, she moved through the apartment she knew intimately and found an eight-inch woodworking knife, hid it in her clothing, and sat down to wait for him to come home.

The Attack

When Tsukasa refused her one final time, Mai pulled out the knife and attacked, stabbing him repeatedly in the chest and abdomen. He tried to fight back barehanded but was no match for the blade and eventually collapsed — still alive. Mai then retrieved a necktie from the closet, wrapped it around his neck, and strangled him until he stopped moving.

Afterward, she sat in a daze before calling her mother: "I got into a fight with Tsukasa and I killed him. Now I'm going to kill myself." Her mother called police immediately. Officers arrived to find Tsukasa dead and Mai covered in blood, with injuries to her fingers and signs of self-harm on her neck; she was treated at a hospital before being arrested the next day, October 30, on charges of home invasion and murder.

Final Thoughts

Tsukasa's autopsy found extensive defensive wounds from the knife attack but almost no resistance marks from the strangulation, suggesting he had no strength left to fight back by that point; the official cause of death was asphyxiation by strangulation. In custody, Mai told wildly inconsistent stories — to her family, that Tsukasa had proposed a suicide pact; to paramedics, that he'd attacked her first and she'd acted in self-defense; in another interview, that she was simply dying alongside a boyfriend who wanted to die. Investigators concluded her actions were premeditated from the start, pointing to the deliberate steps she'd taken — securing entry through a locksmith, locating a weapon in advance, and waiting for him to return — as evidence of calculated revenge for the breakup rather than a spontaneous act.

At trial beginning July 25, 2022, Mai continued insisting the killing was accidental or self-defense, still attempting to shift blame onto Tsukasa. The court rejected her account entirely, and on September 5, 2022, sentenced her to fifteen years in prison. With no reported appeal, she is believed to be serving her sentence.
