Shikimitani Pharmaceutical Research Institute, a suspicious facility known only to a limited few.

The researchers there rely on two dedicated delivery men, Tomoru Onizuka and Togo Kyozaki. Receiving messages from the eccentric and mysterious researchers, the two drive their van deep into the mountains.

——It seems the researchers have sent a message already.

╭━━━━━━━━━━━━━━━━━━━━━━╮ I need a refill on supplies and coffee beans. The brand is the usual one. ╰━v━━━━━━━━━━━━━━━━━━━━╯

╭━━━━━━━━━━━━━━━━━━━━━━╮ I'd like to request delivery of hair oil, sewing thread, and the sculpture I ordered. It's a precious work of mine, so please handle it with care. ╰━━━━━━━━━━━━━━━━━━━v━━╯

╭━━━━━━━━━━━━━━━━━━━━━━╮ I ran out of fertilizer for my flowers and vegetables, so could you buy some? Also, if possible, I might want some tomato seedlings. Could you do that for me~? ╰━v━━━━━━━━━━━━━━━━━━━━╯

╭━━━━━━━━━━━━━━━━━━━━━━╮ Out of energy drinks and chips, so restock 'em. Also, that game that just came out, and ████, and [DELETED], and [CENSORED]. Oh, and I want you to transport a drug I made the other day. Well, I'll talk about the details later. Thanks in advance~ ╰━━━━━━━━━━━━━━━━━━━━v━╯

...And so, these two are jerked around day after day.
