My First (?) Housekeeping - S1.E10

While bootstrapping herself to begin another school day, Mafuyu notices that it is more difficult for her brassiere to contain her mammaries; a brief appraisal later, Tomo decides to make a plaster cast of Mafuyu's mammaries to commemorate the milestone. Miyuri pulls Mafuyu and Sasha aside to relay a story about a man that accosted the soft-spoken student representative Mitarae in his search for Akari; while no real damage was done, Miyuri nonetheless wishes the molester captured or repulsed and it falls on Mafuyu to bring this about. Upon departing with Teresa and Sasha to prosecute a nocturnal patrol, Mafuyu charges Tomo vigilance over the house just as Elizabeth is heading out for a nocturnal practice session armed with an admonition for vigilance against hostile Qwasers; on this ironic note, Tomo's clumsy cooking attempt becomes the deus ex machina to lure out an inept Qwaser named Joshua Phrygianos who guides Tomo through the basics of cooking and wishes to turn the tables on the other Qwasers that have maltreated him. In spite of the nocturnal cat-and-mouse wild goose chase between Elizabeth and Sasha, Tomo and Joshua ultimately develop a novel insightful perspective on their respective lives.
