13 Month Series

13 Month Series are the sentient weapons made by a craftsmaster, Ashul Edwaru. They are given only to the daughters, or Princesses, of King Zahard.

13 Month Series are like half beings, they have human forms sealed within the weapons, that come out and unleash the extreme powers of the weapon when they are Ignited by the user. (Although the weapon may not Ignite for any user, it depends on their personality, for example, the Black March will only activate for "Good Looking" men).

13 Month Series are symbolic weapons. When a Princess is given one of the series, they automatically take part in a certain rule. Some princesses, such as Heice Zahard, refused the series because of this.


 * 1) The Princesses appear to be able to kill each other as they wish to obtain the other 13 Month Series as long as the whereabouts of the 13 Month Series in question is still known (shown when Zahard didn't care when Garam killed Uram and seized the Indigo July, but cared once she went missing with it).
 * 2) However, they may not give or even lend a 13 Month weapon to another person or they will be executed by the King. This is evident from Chapter 2 where we see the conversation between Evan Edrok and Yuri Zahard about the Black March. And it is likely anyone who was accompanying the Princess would be executed too, for failing to prevent the 13 Month Weapon from leaving her hands. And it is also unknown what punishment is meted by the King, when they go missing with a 13 Month Weapon.

The weapons vary in shape and function, for instance, one is a Needle, another a Hook, and the Rainbow is actually an Arms Inventory rather than a weapon. The only S-Rank weapon among the 13 Month Series is the Gold November.

The 13 Month Series are however not necessarily the strongest weapons of their type, but they are all seemingly unique compared to other weapons in the tower, being that they are all sentient and only ignitable if the weapon will let you, it doesn't matter how skilled any individual is they cannot force a 13 Month Series to ignite (for example Yuri Zahard being ranked roughly 500th was and so far still is unable to ignite the Black March).

Notes and Trivia
The 13 Month Series all have their name engraved on them. The engraving is in Japanese, this is because their creator Ashul Edwaru use a language based on Japanese. SIU have (in his blog) made it clear that their not is any significance behind this. And that the use of other languages also will occur.
