Who Killed Sohei Kuruma?

While the obvious answer to who killed the old man is that his son and daughter-in-law were involved in the murder, as Kuruma didn’t sign off his will to his son, another twist is revealed right at the end.

After a point, Sohei’s son poses as if his father died naturally during the cruise. Calling upon the cruise’s Captain, other officials try to look into the matter, and at the time, Sohei’s burnt hand is also revealed, which wasn’t looked at earlier. It doesn’t seem to add up as to how his hand got hurt in the process because the first scene of the film itself revealed that his daughter-in-law had pushed him into the water first, and then he was drowned a second time, as well, by a hooded figure.

Only at the very end do the two couples at odds with each other end up revealing something consequential. The cruise butler, Suguru, finally confronts Sohei’s son, and the gang gathers up.

Suguru presents the newly surfaced video proof, answering questions about the murder mystery. Shiori, the actress, reveals that while her partner was filming, they’d got Sohei’s son and his wife on camera, too. However, since the second time, the person who pushed Sohei was hooded, his son pins the blame on his wife, and to prove his case, he, too, pulls out a video proof.

Why Did Sohei’s Grand Daughter Drown the Old Man?

Before his demise, Sohei had figured out that his granddaughter, Rena, wasn’t related to him by blood and that she’d been born out of marriage, not making her the biological daughter of his son.

Chizuru eventually senses something afoot, places the two phone videos parallel, and notices that the moon is at a different position in both videos, hinting at the time difference, especially considering the Captain had commanded to change the cruise ship’s direction. It proves that the man was pushed into the pool twice, but it wasn’t Sohei’s son who did it because he was already in the room with her wife later on, after she’d already pushed the old man into the pool the first time.

Then it hits Sohei’s son that when they had brought the old man’s body in to play-pretend that he was still alive, his father’s body didn’t have any excessive water in it, which means that he was already dead before he hit the water. Moreover, his burnt hand indicated that he could’ve been electrocuted.

Who Electrocuted the Old Man and Why?

The cat is finally let out of the bag when Magician Edward comes forward after all their speculations. Halfway into the movie, we see his magic stick generating an electric current, and the primary asset helping him with his tricks goes out of power. In the end, Edward reveals that his weapon has been broken. So What happened, and how does he figure into this mess?

The picture becomes clearer. After being pushed into the pool by the other lady, the old man somehow got closer to the pool’s edge, and that’s when the magician extended his stick to him for help. He pulled him out of the water and confronted Sohei about something, but ultimately, he ended up electrocuting him, which is when the ship’s lights also went out.

The story then links back to what Sohei had told his son’s wife earlier about a case from his old days as a doctor. It was Edward whose wife was under Sohei’s care back then. But when a cabinet minister sent out a patient who urgently needed an organ transplant, Sohei was cajoled into tricking a woman who’d just been married and was to be operated on by him.

Betraying the young woman, he carried on the organ transplant operation for the other person by basically stealing it from her body, to put it in crass words. This woman died, and the Sohei thought that he was in the clear since her husband would be grieving for her and wouldn’t pay heed to a missing organ.

Even though the old man had been regretting what he’d done, he ultimately paid for his sins as Magician Edward was none other than that woman’s husband, and he succeeded in exacting his revenge on Sohei.
