Pumpkin

Roman Artillery: Pumpkin is an offensive gun-type Teigu. It seems to have a case with different parts in it, which can be detached and attached to modify Pumpkin. It is currently wielded by Mein and was formerly used by Najenda.

Abilities
It can gather spirit energy and fire it in a concentrated shockwave. One of its main properties is that its power and range increase in proportion to the level of danger its user is in. It's capable of rapid-fire burst shots of spirit energy and has detachable high tech scouter in a compartment that fits around the user's eye. It also has a scope for sniping. It has multiple parts that can be used to modify its power.

With a certain part, it can be used to cut the enemy with spirit energy as if it was a blade. Pumpkin will overheat and be unusable for a certain period of time after using this.

It fires using the user's emotions. Having a higher intensity of passion can make Pumpkin stronger.
