A SHOCKING picture shows a blood-soaked woman calmly smoking a cigarette while on the phone next to her boyfriend who she has just allegedly stabbed.

In a bizarre twist to a case that has gripped Japan, suspect Yuka Takaoka, 21, has become a social media star with fans saying she’s “too beautiful to be an attempted murder suspect”.

Takaoka has now been charged with the attempted murder of her boyfriend Phoenix Luna, who is recovering from his injuries.

While he was lying on the ground naked with his abdomen sliced open, Takaoka can be seen calmly puffing away while on the phone, reportedly talking to a friend.

She seems oblivious to the police officers who have arrived after being called to the lobby of their flat in Tokyo’s Shinjuku Ward.

Takaoka is alleged to have stabbed him twice in their fifty floor flat at around 4pm after an argument broke out when she spotted a photo of another woman on his phone.

“Since I loved him so much, I just couldn’t help it. After killing (him), I, too, wanted to die,” Takaoka told police after her arrest, according to local media.

The incident took place on May 23 and following her arrest, her fame rocketed after being filmed smiling in the back of a police car.

According to the Tokyo Reporter, her popularity stems from fans likening her to an anime character, known in Japanese culture as “yandere”.

The character often takes the form of a schoolgirl who eventually becomes aggressive and homicidal.

Fans on dozens of Instagram and Twitter accounts share pictures, video and screengrabs.

They speculate about her jealous and obsessive nature and share photographs of her bizarre behaviour as well as the grisly crime scene.

They include tribute art showing Takaoka stabbing Mr Luna or flashing a smile while brandishing a bloody knife as a cigarette dangles from her lips.

More details have recently emerged about the incident that propelled her to fame.

According to Japanese media, Takaoka was working as the manager of a so-called “girl’s bar” — a type of hostess club when she met Mr Luna in October last year.

Blessed with boyband good looks, Mr Luna was a bar host at Fusion nightclub in the Kabukicho red-light district.

Employees at the club are ranked according to their popularity and Mr Luna had reached number 4 on the ladder.

Like their female counterparts, male bar hosts are expected to generate sales by flirting with patrons and encouraging them to keep drinking.

The pair decided to move in together and on the night Takaoka allegedly stabbed Mr Luna, they had been sharing an apartment for just three days.

But he appears not to be bitter and even credits the incident with boosting his popularity at Fusion and reuniting him with his estranged siblings, who came to see him in hospital.

“I do not hold a grudge,” he told Tokyo Reporter last week.

“I think there was a reason for her to stab me. It was also thanks to her that I was able to achieve the sales that I did in less than a year since I became a host.”
