Tsuruchi Etsui

Tsuruchi Etsui is the head guard of the Mantis Clan estates in Toshi Ranbo wo Shien Shite Reigisaho, and a former member of the Kolat.

Battle of the Tomb
Recently he prepared a group of guards under the command of Yoritomo Katoa to find and protect the Emperor in his travel to the Shadowlands, seeking the Tomb of the Seven Thunders. He also made a deal with Yasuki Jinn-Kuen for travel arrangements. Etsui was the last person to speak with Emperor Toturi III before his death.

After the Battle of the Tomb, Etsui delivered the Candle of Shadows he found at the Tomb (and whose function is still unknown) to Yoritomo Yoyonagi. He also kept another yet unidentified relic (a silver baton with hidden blades) and showed it to a Kolat contact, Shiba Yoma. To this contact alone he also shared that the now-dead Toturi III revealed to him how to find the information about his wishes on the sucessor to the throne.

Winter Court - 1170
Etsui spent Winter Court at Kyuden Kumiko in 1170, where he again met up with Shiba Yoma. The two were discussing possible kolat contacts and recruits, but were interrupted by Yoritomo Yashinko.

Fall of Lady Moon
Haunted by his betrayal of Naseru's trust, Etsui turned his back on the Kolat by killing Master Silk. Shortly thereafter, he encountered the dying Hitomi, who had been cast down from Tengoku by the Obsidian Dragon. She tasked him with bringing her last words to the Dragon Clan.

Sixth Imperial Legion Command
As part of the rbuilding process in the aftermath of the War of Fire, Etsui was appointed to head the Sixth Imperial Legion at the behest of Emerald Champion Shosuro Jimen.
