Tokyo Ghoul Review

My recent favorite animation is "Tokyo Ghoul" written by Sui Ishida. This animation is a dark fantasy and modern Tokyo is the stage. There are monsters who look like people called "Ghouls". Ghouls eat people. Why do you think Ghouls eat people? Because Ghouls can eat only people.

The main character is Ken Kaneki who is a university student. One day, a certain accident happens and Ken is implanted with a Ghoul's organ. This is how Ken becomes a half-Ghoul. If he doesn't eat people, he will die, but he doesn't want to eat people. He struggles at the threshold between human and Ghoul. Neither world is a good place for him to stay. He is accepted by Yoshimura, who is a Ghoul, and a coffeehouse manager―Anteiku. Yoshimura says to Ken "You are only one person who can have the world of human and Ghoul"

I watched all of the episodes of this animation, but I can't understand the last scene. If you watch this animation, please tell me what the meaning of the last scene is!!
※This animation, Tokyo Ghoul, has a lot of grotesque scenes.
