Banmaru Zoushi


Banmaru Zoushi is a gadget master allied with Tenma Ganzo who aspired to become a Juttensen. After Rushuna defeats him he joins Touka, drawing up plans for the reconstruction of Peach Blossom Tower. Banmaru later constructs a massive cannon using the Peach Blossom Tower as a base that can fire a shell all the way to the capital to deliver Touka Kurenai there quickly after she receives Mikan's balloon-delivered urgent request for assistance. source: wikipedia
