A SMG with two blades that have a powerfully retractable wire attached to both ends of the blades to also be a bow. Arrows are fixated with either an explosive on the pointed end or a zipline on the feathered end. Can also transform by aligning parallel and extending the blades to be a claw type weapon. The wire can also be used to flail the SMG blades like a sicke on a chain.
The katana is manufactured with electric charges to either create shockwaves or a high frequency on the blade. Activated by griping the hilt. More pressure means more power. It's name comes from combining the word katana with kaminari, which roughly means godly lightning, also known as thunder.
