 Navy
 Warring States: Hammer! The navy's funds are insufficient this year. You quickly build a batch of luxury swords, and I'll go find the Celestial Dragons in exchange for money!
﻿﻿Akainu: Hammer, I need another version of the glove you made for me. The red hair chopped the previous one into pieces.
Zefa: Hammer! Be honest and become a general. Don't always think about being a logistics minister!
　　Pirate:
　　Kaido: Damn Hammer, what did I do to my Hachisei! Why can't it get hard?
﻿Red Hair: Damn hammer, how dare you hit me...
﻿Hawkeye: My Black Blade Ye has successfully evolved into the Black Blade Riye. There is always a singing sound when I wave it...
﻿﻿Dragon people:
I have a luxurious bed made of hammer!
  cut! I have a onesie made by Hammer!
