Mr. Rai is my best friend.

Crossing the rapids is difficult.

I heard the sound of the swift current, and my heart calmed down.

He was suffering from leprosy.

In old Japan, leprosy was considered an incurable disease.

When the wind blows, you can hear the rattling sound of the wind.

His face was deeply etched with wrinkles.

I was scared because there was thunder last night.

It's scary to walk in a thunderstorm.

Kaminari is always a bright and energetic person.
