I thought we could win by delegating to others? (他人任せで勝てると思った？ Taninmakase de Kateru to Omotta? ) is the eleventh episode of the Netoge no Yome wa Onnanoko Janai to Omotta? series. It aired June 16, 2016.
Rusian and the others include Nekohime and Sette, and recruit the top-ranked PvP guild "Wallenstein" to bolster their ranks. With the additional help, Guild Alley Cats charges in to take over Fort Cantor, but not everything goes according to plan.
Master and Wallenstein's leader Bats make a formal alliance to help Alley Cats win their siege battle. Evaluating the guild members one by one, Bats gives Alley Cats a vague strategy rundown assuring that his guild can handle the dirty work, with Akane and Nanako capitalizing on his pretentious attitude. Arriving at Fort Cantor with defending guild Emperor Sword on guard, Bats instructs Ako and Sette to run across opposite sides of the castle, spreading out their stationary guards. As Rusian and Schwein charge the defending line, Alley Cats soon witness Wallenstein's true power as they eliminate the entire defending party with little effort, instructing the others to take cover. Once the carnage begins to clear, Ako and Sette runs inside and regroups with the others, where Fort Cantor becomes captured in the name of Alley Cats. While Wallenstein takes their leave, the group feels unsatisfied with their easy victory feeling somewhat unaccomplished. However, once their moment of reprieve is up, Bats instantly dissolves the alliance and stages a takeover on the castle, single-handedly killing every guild member except for a grief-stricken Ako. While real world Ako procures maid outfits from Kyo's maids for her class' maid cafe, more problems arise as she neglects shift duties and serving manuals a week before the cultural festival, to which Hideki helps her classmates become notified. On the matter of taking revenge on Wallenstein, Hideki forms alliances with Nekohime's Elite Guard as well as the Dark Magician's guild TMW. With only one more siege battle before the culture festival, will their combined efforts be enough to take down Wallenstein?
