Akumaro Sujigarano

Akumaro Sujigarano (筋殻 アクマロ, Sujigarano Akumaro) (27 - 43) is a Gedoushu general. Previously sealed away within the bottom of the Sanzu River, the overflowing energy of Dokoku Chimatsuri due to a summer-increase in power gave him the energy to re-emerge on the surface. He is able to create monsters called Kirigami (translates into "Cut-Out God", just like how "Origami" is "Folding God") by performing kirigami, as well as has a specific army of Ayakashi loyal only to him. His left shoulder region is apparently his weak spot, as he has been struck there with considerable pain by Doukoku during an argument and by Shinken Gold during battle.

Biography
Although claiming to assist Doukoku's on his own means of conquest, Akumaro secretly held his own dark desires he kept hidden from the general. In the midst of the battles with the Shinkenger, he specifically started to target several specific "points" in Japan where the Ayakashi would not merely create fear but collect it at that particular location where it would collect in the ground. At the same time, he began to collect notable artifacts, including Dayuu Usukawa's shamisen and Juzo Fuwa's sword Uramasa, claiming to Doukoku that he would repair them due to their damage but ultimately holding on to them for his own plans. This would force both of them to ally in order to get what they want back; this alliance would also be the first to encounter the angelic squadron of the Tensou Sentai Goseiger.

Due to the loss of Dayuu and her shamisen becoming too unbearable, Doukoku ultimately was forced to take it back from Akumaro while risking nearly getting himself killed in the Human World due to rapid water loss, with Doukoku not wanting to repair the instrument but instead use the misery of Shinza (the human used to create it) for his own plans.

Ultimately, Akumaro's plan was not to assist Doukoku in raising the Sanzu River but to manipulate several points of weakness in Japan which would ultimately open a gate to Hell, consuming everything (including Earth and the Sanzu) in the process. Due to his own nature of being a fallen "Gedou", Akumaro knew he would never experience Hell and was trapped within his own existence, thus his obsessive desire to bring Hell forth so he could know of it's existence. For that ends, he also created his greatest "weapon": Juzo Fuwa and his sword Uramasa, made from the souls of his family for the purpose of having a human/Gedou hybrid who could open the Hell gate and therefore unleash the horror upon the world.

However, Akumaro's great plan also lead to his downfall: when finally giving Juzo his sword back to complete the gate, the fallen warrior slashed him with Uramasa, claiming that he knew of the souls of his family being in the sword long ago and chose to remain a Gedou to satisfy his desire to fight. With Akumaro rampaging, the Shinkengers put him down once, while his "second life" took everything the six samurai had until a combination of all 12 of their Origami (the Samurai Ha-Oh combination armed with the Kyoryu Origami) finally put him down. In his last moments, Akumaro showed elation as he died, he finally getting a chance to see Hell in all of its glory.
