Gouki is my best friend.

The porcupine is a nocturnal animal that protects itself with its sharp quills.

He was pursued by bad luck all his life.

He is a person of great luck.

In traditional cosmology, Kakuun is considered one of the triangles.

As a campaigner, he is promoting a healthy lifestyle.

Let's buy a lottery ticket today to try our luck.

He has been having bad luck recently.

He loves games of luck and plays for several hours every day.

He is a klutz and can't play sports at all.
