Fodlan generations ago learned of the continent a sea south of them which are inhabited by strange people. These people seem to be less civilized then them and do not possess the power of crests so the Empire quickly took their opportunity and occupied the smaller continent. Now in the year 1180 Garreg Mach has finally accepted their request to gift them a 4th House where their eight brightest youths will be taught, a perfect cover up for their plan.
Now, it is the day where Princess Daku and seven other youths travel to Garreg Mach.
...
The large ship shook due to the high waves that crashed against its wooden sides lulling the eight young boys, girls, and one futanari to sleep. Princess Daku however couldn't sleep not yet at least. She has been waiting for this moment her entire life her parents and grandparents - Hell! Everyone she knew waited and trained her for this moment, this single opportunity. It was a perfect time too the Empire was in turmoil, the Kingdom had a young king, and the Alliance's head was old and dying and will probably be dead in less then 5 years. She just couldn't sleep.
A good thing too because it was then when the ship was hit by a new force, cannon fire.
"Pirates!" Daku scowled as she grabbed her weapon, an iron sword, and armor before waking up her roommate and bodyguard, Ryuji.
"Huh? Oh!" He quickly got the message as he grabbed his iron axe and prepared for a fight.
As they rushed out Daku saw her future classmates also out and prepared to fight. Dust an archer, Haku a duelist, Akane a mage, Tina a cleric, Travis a lance wielder, and Sienna also a lance wielder. It was a good thing too as the pirates have managed to cross the wooden planks onto their ship. A total of ten of them plus what seemed to be their leader, a burly woman the others called boss, before the ballista finally killed the remaining pirates back on their ship.
"Oi! You'll pay for this, with your gold, bodies, and lives!" The head pirate said in anger.
"Leave them to us. We'll deal with these idiots." You said calmly to the remaining other soldiers who wished to join you. You wanted to test all that you have done so far. "Let's see what we can do!" You shouted as the eight of you charged to confront the pirates.
The battle was easy for the younglings who easily dispatched most of the pirate crew, some more lethal then others. The only one remaining was the boss, Augusta.
"You brats are stronger then you look! That just means you'll fetch a higher price!" Augusta said in a mocking tone. Daku readies herself before she took her stance and waited. Sure enough, Augusta took the first hit and paid for it, with Daku easily countering and subduing the pirate boss with her iron sword. "Agh! You gonna kill me now?"
Daku didn't ponder a second, after all, she has yet to test out her special dark magic yet. "No. You are too good looking, despite your profession, for that." She said simply as a dark purple glyph appeared below and above Augusta. Dark purple smoke engulfed her hiding her from view as the spell begin it's work.
"Ah! Ah! No! What's happening to me!?" Augusta screamed as her shadow, the only thing that could be seen, shifted, and morphed as she screamed her head off. "Oh! What is this feeling?" Her voice wondered, stopping her screaming. Everyone noted how her voice sounded less gruff and more feminine.
Quickly after the smoke and glyphs cleared leaving a naked Augusta moaning as she pleasured herself. Augusta clearly changed from her past self, now her skin purple and her untidy hair now a red color formally a brown color. Her form also changed, her muscles were slimmer yet still tones along with her body conventionally more attractive. With her breasts now a CC cup and with an ass to match.
"Who am I to you?" Daku asked.
"Y-you are my mistress." Augusta said in a sultry voice as she stood at attention, confirming her voice change. Daku smiled at this before ushering her classmates and her new corrupted into their beds, sharing hers with Augusta.
"Ryuji, can you help the crew fixing up the ship?" Daku asked kindly though a hidden purpose beneath her request. Ryuji understood and left her with Augusta.
Daku turned to Augusta, "Now, how do I make this official?"
