Clean-Up Duty, with the Slimes

Suraimu-tachi to Seisō Sagyō (スライムたちと清掃作業)

With help from his slimes, Ryoma not only cleans Miya's house, but make some repairs on it, much to her joy, and she increases his reward out of gratitude. In his next job, Ryoma is tasked to clean the communal toilets, amid suspicions that the toilets are not being properly maintained due to embezzlement perpetrated by the local authorities. While Reinhart investigates the matter, Ryoma discovers that the toilets are contaminated with miasma. 

Upon knowing of this, the Jamil family attempts to dissuade Ryoma from continuing the task, but he convinces them that he is the most suited for it. The guild then sends Miya along with some other adventurers to keep the population away from the toilets until Ryoma completes the cleaning. After the job is done, Ryoma reminisces about his mother, who used to stay awake to welcome him home after work until her death, and cries tears of joy when the Jamil family welcomes him home in a similar fashion.
