==History==
=== TV Series ===
In the late summer of 2005, Eiki was following some rumors of Makamou activity to Kayanoki mountain and found evidence of a Tsuchigumo, but something was strange about its behaviour. He sent out his Disk Animals and was able to locate them. He called the Tachibana Sweet Place and reported to Hinaka Tachibana his suspicions and that he was going to exterminate it. He transformed and ran through the forest clad mountain until he found them in an old quarry. They taunted him to come their way and Eiki said he knew they were Tsuchigumo and that he had been looking for them. The Douji and Hime transformed into their armored forms and trans-morphed weapons. Eiki unholstered his Ongekibou as he noted they were warrior forms.
They started duelling but the versatility of the Douji and Hime in the confined space proved too much. They knocked him down and the Douji stabbed Eiki in the leg with its weapon, while Hime knocked away one of his Ongekibou. Eiki saw not other way and started to flee until he came to a cliff. The Douji threw its weapon at him and it graced him hard enough so that he fell of into the river far below. 
Some mountain folk found him and saved him from the stream. They got in contact with Takeshi and said that he was safe but hurt. Eiki spent the night with them and managed to heal his leg injury. On the next morning he headed back to his camp where Zanki and Ibuki's disciple, Akira Amami gave him the location of the Tsuchigumo.
When Eiki arrived, Todoroki was halfway into the Makamou's mouth, so he ran and bashed the Makamou's head with his Kiboujutsu Rekkadan charged Ongekibou. The impact made it release its grip on Todoroki and both Eiki and Ibuki ran up to him to see how he was. He was fine but Ibuki wondered about Eiki as well. The Oni replied that after a night's sleep he had restored his 'eiki' (high spirits), so he was fine. They all rushed towards the Tsuchigumo, and Eiki jumped up on a rock to its side and attached his Ongekiko to use his Ongekida Hissatsuhitchu style, while Ibuki used his Ongekisha Shippuuissen technique and Todoroki jumped up on it and used his Ongekizan Raidengekishin technique. They played until the Makamou started rampaging, destroying the rock Eiki stood on and shaking Todoroki of. They were about to follow it, but the Douji stood in their way. Eiki disarmed it and hit it twice with the Rekkadan, while Ibuki kicked it with his Kitoujutsu Senpuujin and Todoroki slashed it with his electric charged Ongekigen which destroyed the Douji.
The Oni ran after the Makamou, but when they caught up with it they saw that Hibiki had already defeated it. They greeted him and he greeted them back.
