Kinou no Wanko

Kinou no Wanko (昨日のわんこ) is a Felinoid Samurai in the Black Sword Knights.

Appearance
Kinou is a tall Felinoid with black fur and a white muzzle and white paw-like hands. He wears an aikidogi along with a brown scarf around his shoulders.

Round Table Alliance arc
Kinou can be seen when Marielle talks to Shiroe about the Black Sword Knights' usage of EXP Pots from Hamelin, which was taking advantage of new players.

Later, Akatsuki is spying on a Hamelin member when Kinou meets up with him to buy EXP Pots, an opportunity she uses to get the Hamelin member's username as part of Shiroe's plan.

Summer Training arc
Along with Rezarick, Kinou serves as one of the Black Sword representatives for the Summer Training camp. When the Sahuagin begin attacking en masse, he and the other teachers band together to buy time for the lower-leveled players to escape.

Noosphere arc
Kinou is dispatched to Maihama per the Round Table directive to have the Black Sword Knights train the Glass Greaves, the city's knights. He is seen overseeing drills and giving advice to the Earthling knights. He would stay in Maihama as the Black Sword Knights permanently move their headquarters to Maihama during the events of the Collapse of the Round Table arc, although the guild would remain with the New Round Table Council that formed after the election.

Nightingale's Song arc
Kinou is one of the Black Swords present in Akiba when the Genius Eirenus invades, thus getting sucked into the dungeon it creates along with Isaac, Rezarick, and Kirin-chan. They are the first to come across the Genius at Akiba Station, where their levels are forcibly reduced to 35 by its abuse of the Teacher System.

While it is not shown what becomes of him, he is presumably killed by the level 65 Genius shortly after it kills Isaac.
