This manga is filled with love of people and hate for the shitty company that's made this world worse. Props for the mangaka for being so based and redpilled.
Demons love loosely defined terms in their contracts. It gives them freedom to bullshit. I don't see Mary leaving after her stint in corporate sabotage, since nothing was destroyed physically. Just spirits and finances most likely.
Ah yeah the good old retail & service industry corporate slave, I remember years ago when I worked in retail shop from 7 am to 11 pm with no extra pay for a month because they haven't got replacement for my shift and best of all they even deduct my pay for missing merchandise and give warning letter because I missed the 7 am open shop window (since I hold the shop keys).
Nyahaha! It's time for WAR!
Once again, I don't care about the lewd moments. The biggest power fantasy is the big middle finger to black companies. Let's destroy them all!
