Yasuo is my best friend.

Mr. Kenmikawa became a police officer.

險 is an old font for 険.

He broke the glass.

He played a broken character in his heart.

Electromagnetism is a part of physics that studies the interaction between electricity and magnetism.

He is living a life of shabby clothes and plain food.

He was kept uninformed about the important decisions of the company.

He is living like a riverbank beggar.

I use a microscope for biology experiments.
