Ignition Weapon

An Ignition Weapon is a powerful type of weapon used in the Tower. An Ignition weapon is said to be a weapon with a soul. However, instead of thinking that all ignition weapons have souls, it's more accurate to say that they're created using a special kind of Shinsoo. When activated (시동, shidong, 始動; "ignite" or "start engine") it releases vast amounts of power, enhancing its speed, damage, etc.

A branch form of Ignition weapons are Compression Weapons. In Ignition mode, certain Compression weapons like the Green April are capable of becoming far more powerful when decompressed. Ignition weapons are supposedly quite rare on the lower Floors of the Tower, as Androssi was very surprised when she first saw Narumada.

An incredibly famous and powerful group of Ignition weapons are the 13 Month Series, which are only given to selected Princesses.

Another type of Ignition weapon are the Living Ignition Weapons, living beings with an Ignition Weapon inserted in them, created after extensive research and experimentation by the scientists of the Workshop. The current known Living Ignition Weapons are Horyang, Cassano, Beta, Jyu Viole Grace (referred to as the "complete product") and Emile.
