Monster Rank (Public Poll) (Patreon)

I spent quite some time thinking of the classifier regarding the monster's ranking system for Demon Sword Maiden. The direct translation would be Low-Rank Initial Stage, Low-Rank Middle Stage, etc.

I felt that the direct translation would be too long. So I came up with several options:

Option A:

• Low-Rank
  Low-Rank+
  Superior Low-Rank
  etc...

Option B:

• Lesser Low-Rank
  Low-Rank
  Superior Low-Rank
  etc...

Option C

• Low-Rank
  Low-Rank+
  Low-Rank++
  etc...

Option D

• Low-Rank
  Low-Rank Plus
  Low-Rank Plus Ultra
  etc...

Option E

• Low Rank-
  Low Rank
  Low Rank+
  etc...

Obviously, I chose option A, but options C is not bad either. What are your thoughts? Which option do you prefer? If there is none, what other option would you suggest?
