Michael Smith always believed that the three core elements of H-anime—Hypnosis, Time Stop, and drugging—were completely overkill for the heroines of this world.
Because you don't need to go through all that trouble; just drag them to a secluded spot, apply a little pressure, and they'll obediently submit. At most, they might protest verbally a few times, but their bodies will be very honest.

But that doesn't mean the 'three core elements' are useless. On the contrary, these abilities are meant to deal with your peers.

Acquiring power is essential; otherwise... this world will be hell for you.
"To survive, what's wrong with being a villain?"
Of course, it would be even better if I had a powerful second brother...
