There are three boys named Akira in the class.

This room is overflowing with happiness.

In this factory, they melt iron using an electric arc furnace.

Mr. Kusanagi is my best friend.

He does yoga every day to increase his body's flexibility.

His heart seems to have frozen.

Please go straight down this road.

His answer was unexpected.

He answered my question immediately.

He keeps the words 'Don't hesitate to correct your mistakes when you make them' in his heart, always striving for self-improvement.
