My Sister's Been Corrupted by Evil! The Only Way to Save Her Was to Turn Me into a Female Superhero That Looks Just like Her!

The master of TSF fiction, Reitou Mikan, is back with another funny and sex story. For a plot summary, you can consult with the title. In addition to the main story, also included is a short 12 pages long story titled “My trainer”, in which a gender swapped guy is being “trained” by his friend on how to act more girly. And the whole thing is government approved, apparently.
