Toshiro Kago

Toshiro Kago is an abducted samurai found aboard Mothership Zeta

Background
Toshiro Kago is one of the four people that the Lone Wanderer thaws out on board Mothership Zeta. As he does not speak English and no other character speaks Japanese, conversation is largely limited to gestures. Kago is a samurai warrior, skilled in sword combat and capable of slaying aliens, should his sword be given back to him.

Quests

 * Among the Stars: Toshiro can be spoken to about his missing sword and the Lone Wanderer can return it to him after retrieving it from the maintenance level.
 * This Galaxy Ain't Big Enough...: During the final battle on the bridge, after the first wave of aliens are defeated, Toshiro will run in from a side door and assist Paulson and Somah in battling the next wave of attackers.

Effects of player's actions
After the events of Mothership Zeta, he stays aboard Zeta and cannot be interacted with. He will disappear if one revisits the Steamworks but will remain on the bridge if the player character travels to or from the Capital Wasteland. He can be found later in the living quarters.

Other interactions
Despite being unable to understand English, Toshiro still responds with different dialogue depending on whether the player speaks to him with the polite, neutral, or smarmy dialogue options.

Inventory

 * * Kago will use the sword if it is either recovered from the waste disposal area and given it to him, or if one never enters the disposal area.
 * * Should the player decide to keep the sword, Kago will remain unarmed.

Appearances
Toshiro Kago appears only in the Fallout 3 add-on Mothership Zeta.

Behind the scenes

 * The Fallout 3 Official Game Guide states Kago's armor is dated to the Azuchi-Momoyama period (A.D. 1568-1603) which is a real world period of Japanese history.
 * The symbol on his tosei dō or breastplate is the real world mon of the Katabami clan. Specifically, the emblem is called maruni ken Katabami (丸に剣片喰), popular among samurai clans during the Heian period (A.D. 794-1185) and used to the current day. A nearly identical tosei dō is a part of Philadelphia's Penn Museum collections.

Bugs
After completing the main quest of Mothership Zeta, with Toshiro still alive, it is possible to pickpocket him. In his inventory, his samurai sword will appear but trying to steal it may result in the game crashing.
