Personality

The Undead King Arc
Prior to YGGDRASIL's silent shutdown at the end of the game, Momonga recalls all the good times the members of the Ainz Ooal Gown including Genjiro in his lamentation of his fellow guildmates' departure a few minutes before him, the Great Tomb of Nazarick and all of its NPCs were transported to the New World.

The Bloody Valkyrie Arc
Ainz reminisces about Genjiro when he goes to the treasury. He remembers he took pleasure in keeping things neat and organized, and would have categorized objects according to their purpose. However, Ainz wonders whether he actually relishes tidiness, because if he truly did, the treasures in the treasury would be managed more orderly, and he would not describe his own room as a mess. Ainz remembers that Genjiro should have already separated the items into categories of armors, weapons, jewelry, auxiliary tools, consumables, manufacturing goods, etc. as well as the Nazarick maintenance room and the crystal data storage room.

Main Equipment

 * Ring of Ainz Ooal Gown: It allows the user to freely teleport between every room inside Nazarick. Every member of Ainz Ooal Gown was required to wear this ring.

Momonga
Genjiro was one of Momonga's friends that had been with him and the other clan members since Nine's Own Goal. Momonga doubts that Genjiro was actually a neat man as he argued, if that was the case, the gold outside the Main Treasury would be more orderly and he would not describe his own room as a mess.
