Operation Tenshu

Operation Tenshu was the code name for a top-secret mission from 63rd to the 87th of Raindawn, 25 2A to hunt down and capture Takira Fukunam and his four associates, who were later discovered to be his sons, by Golden Koi Division S Fireteam 100 after Golden Koi intelligence discovered that he was in the province of Taybobec. The mission failed, with three of the four agents being killed while Takira and his three of his sons evading capture, and only one of them being killed.

Testimony from the sole survivor, Kojo Tsukijo, revealed that Fireteam 100 was given poor intelligence of the capabilities of Takira and his sons, causing them to be severely unprepared for the mission. Intelligence claimed that the fugitives were on the run, but instead intentionally sought out the fireteam, separated them, and killed most of them one by one using highly advanced magic known as hallucinogenic magic.

The foiled operation caused panic among those who were aware of the mission after Mennor's Massacre when it was discovered that two masked humans with Gorukan accents and extremely powerful magic that is believed to be hallucinogenic magic aided in the massacre. The Golden Koi quickly surmised that the men were likely two of Takira's living sons. For a brief moment, it was believed that Gorukai was going to enter the Great Interran War.

In 44 1A, Takira revealed to Tenshu Meito and Kojo that the operation was set up by Emperor Heiwajo to kill Otonira Meito in retaliation for the murder of his wife. Heiwajo used Otonira's death as a way to apologize and prevent Takira from attacking Gorukai. Takira apologized to both Tenshu and Kojo and placed Otonira's urn next to his wife's atop their secret hideout in Mt. Gorukami. Kojo, feeling betrayed by the Golden Koi, and Tenshu, feeling that her father was used as a pawn, forgave Takira and Akamaru and joined forces with them.

Background
Takira was the previous Commander of the Golden Koi who held considerable power during his time leading the Golden Koi. His popularity among both the upper echelons of Gorukan society and as well as the commoners was enough to make Emperor Heiwajo feel threatened. The Emperor sent an agent, later discovered by Akamaru to be Fireteam 100 leader Otonira to murder his wife and imprison his children in an attempt to break Takira's spirit. Takira was sent an ultimatum by Heiwajo; step down and self-exile or his children would be murdered as well. Takira did as told and relocated to Hontam, Greymount along with his children. Heiwajo has secretly controlled the Golden Koi ever since.

Takira's arrival to Baygoi
Following pressure from his sons, Takira returned to Greymount to assassinate Heiwajo. The Golden Koi were immediately known of his presence when he arrived at the city of Baygoi on the 38th of Raindawn and informed the Emperor. Heiwajo, knowing that Takira was likely back in Gorukai to kill him, secretly contacted him and offered to let him kill Otonira and his team in exchange for his and Gorukai's safety, to which Takira reluctantly agreed.

Fireteam 100 was given just a day's notice that they were to go after Takira. Hiraka of Fireteam 44 and Ayür of Fireteam 67 was also ordered to standby in case backup was needed. On the first day of the operation, Takira and his sons split up and left Baygoi.

Cuhuay Hu confrontation
Akamaru was the first to leave his father and siblings and traveled to Luqi Ling. He traveled to the village of Cuhuay Hu and lived in the village's ryokan, waiting for the agents to show up. Agent Feishira, a native of Luqi Ling, split up from the rest of the group in Taybobec when Golden Koi intelligence informed them that one of Takira's "associates" had left the group and was hiding in western Luqi Ling.

After searching fruitlessly throughout western Luqi Ling, Feishira arrived at Cuhuay Hu on the 74th of Raindawn after a passing herder told him of a strange masked Gorukan who had been living in Cuhuay Hu's ryokan. Feishira and Akamaru immediately noticed each other upon seeing each other in the ryokan. Both were dressed much better than the poor villagers in Cuhuay Hu and both were the only ones carrying swords. Akamaru attempted to leave the ryokan but was blocked by Feishira, forcing him to blow the door open with pyromancy.

A fight between the two spellswords commenced in the village. Both had taken serious blows in their first fight in the village and required serious medical attention. Akamaru fled the village and to a nearby pier, with Feishira quickly catching up with him. Feishira, too exhausted to continue fighting with his sword, activated his hallucinogenic magic with the last of his energy, forcing Akamaru to activate his hallucinogenic magic. The two continued to fight in the Hallucinogenic Plane, with Akamaru's dragon against Feishira's squid. Akamaru defeated Feishira after a fierce battle which forced the both of them back into the Material Plane. Feishira laid on the ground incapacitated, Akamaru who could barely move, slowly dragged his body to Feishira, thanked him for the battle, and promised him that his comrades would retrieve his body. Akamaru took his sword and ran it through Feishira's stomach, killing him, and fired Feishira's flare.

It is unknown where Akamaru went to recover after the battle, but he sent out a message to his father and brothers to let them know that the Golden Koi agents had also mastered hallucinogenic magic and to take them very seriously. Ayür retrieved Feishira's body.

Karito's ambush
Karito and the rest of the Fireteam left Taybobec and traveled to the province of Qalaq
