He is my greatest enemy.

He is my enemy.

He killed the enemy with a sword.

There is no one who can rival his skills.

We visited the beautiful castle in Kyoto over the weekend.

It is said that an old king used to live in this castle.

This old castle is not used anymore.

We are planning to visit the castle this weekend.

This old castle tells the history of Japan.

This castle has existed since the medieval times.
