Ignition Weapon

An Ignition Weapon is a powerful type of weapon used in the Tower. Ignition weapon is said to be a weapon with a soul. It is made with a shinsoo holding a soul. 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 called the 13 Month Series which are only given to selected princess. While some Ignition weapons such as those in the 13 Month Series do have souls, not all of them do. They are all constructed with special shinsoo.

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 made by the Gong Bang. The current known Living Ignition Weapons are the Devils Horyang and Cassano, Beta, Jyu Viole Grace (refered to as the "complete product") and Emile.
