[Multiple heroines + invincibility + system + back room + suspense + indecisive killing + science fiction + Cthulhu + Warhammer] "First, from now on, you will not be harmed in any way, whether it is physical or mental, and you will be immune to all negative influences." "Second, you will not be trapped in any way. Whether it is a confinement in space or a stagnation in time, you can come and go freely and unimpeded." "Third, you will have an unlimited storage space, which exists in a special dimension called the 'back room'. However, it is not peaceful there, and there are many terrifying entities wandering there. Of course, with your current four abilities (absolute loyalty, immunity to damage, not trapped, and unlimited space), you should be able to walk sideways there." "Boy, in other world lines, I have tried to issue tasks to let you unlock your power step by step and improve your abilities." "But it turned out that it was too slow, and there was no time to deal with the coming apocalypse." "So, this time, I will simply give you all my power and authority at once." "Whether it's a dragon or an insect, it all depends on your own destiny." "Farewell, boy." "Good luck to you."
