4 Answers. Minoru died because of Ryuk, similar to how Yagami Light did. Through the original Death Note Series Ryuk mentions that when the owners life would come to an end, he would write down the name instead.

Why did Ryuk killed Minoru?

Minoru is killed by Ryuk for breaking the “no sale” rule, but Trump saves his own life. Even though Minoru did not once use the Death Note for its deadly powers like Light did, he was still killed for a rule instituted after the fact, as if the goal posts had been moved.

Can Ryuk kill anyone?

Ryuk cannot, under any circumstances, kill another Shinigami with his Death Note. ... On top of this, not being able to kill another Shinigami is boring, too. So Ryuk's only choice of stimulation is to head to the human realm and see some killing up close.
