- 武 — martial strength, warrior
- 瑠 — lapis lazuli, precious force
- 功 — achievement, dominant merit
- 須 — commanding necessity, must
武 and 瑠 merge the disciplined force of a battle-hardened warrior with the rare and precious brilliance of lapis, as 功 tallies the great achievements of conquest and 須 demands absolute and unquestioning authority from all.
