Cheat Kusushi no Slow Life: Isekai ni Tsukurou Drugstore

Synopsis

"Dishwashing Detergent Scrubba-dub-dub": Reiji creates detergent to make cleaning easier for Mina. Doz and Moz, Red Cat mercenaries who protect the town, beg Reiji to sell his energy potions for a discount as their Captain Annabelle requires five a day due to how hard she works. Reiji agrees to provide them for free if they help advertise his detergent to the townspeople. Annabelle agrees after seeing how easily the detergent washes dishes and also insists on collecting her potions herself.

"Beast-Be-Gone": The forest begins running out of herbs so Reiji decides to grow them in fields loaned to him by Zeral, the Alonzo field. Unfortunately, pests have begun damaging crops so Reiji creates a beast repellent from the Utsubo flowers that repels the pests but is undetectable to humans. The repellant is an instant hit with farmers but Noela refuses to be around Reiji unless he has bathed first, due to her heightened sense of smell.

"Capshin Fluid": Annabelle reveals bandits have appeared recently and she needs extra potions for her injured soldiers. Reiji creates a potion from alcohol and Capshin Peppers which, when sprayed in the bandits faces causes unbearable pain in the eyes and nose. Shortly later, the bandits leave the area forever. Elsewhere, Reiji's energy potion comes to the attention of someone powerful, the Demon Lord.
