He remains calm even in difficult situations.

He is fighting on the front line.

He took out his wallet from his pocket.

In order to go to Osaka, I will pack my luggage tomorrow morning.

He understands the meaning of 'datsu'.

I tried sounding him out about the new project.

He put his hand out of the window to check if it was raining.

He was a great assistance to my project.

Please help me, I got lost.

I sincerely thank you for your help.
