Oni

Sophia took John to the manor's dungeon.

"The Order keeps some monster they've captured alive" she said, "we have new recruits train by fighting against them"

Sophia opened the door to the cell. John stepped inside to see an Oni.

John knew about Onis. They were humans mutated into demons. Why hadn't she been exorcised? Suddenly Sophia closed the cell door.

"What is the meaning of this?!" demanded John.

"To prove yourself" said Sophia.

"No, I mean keeping an Oni in here?"

"Onis cannot be cured" said Sophia.

"Why keep her in here?" asked John, "her suffering should be ended"

"She was part of an organisation that deals in sexual slavery. To become a member, you must kill or sell your entire family. They tried summoning an Oni to kill a rival organisation called the Many. Instead the Oni possessed this woman and killed the rest of her organisation. If you think she deserves mercy, then grant it yourself"

John returned to the dungeon and began to fight the Oni. Unfortunately, his attacks barely damaged the Oni. The Oni swung her club at John but he blocked it with his shield. John barely dodged the creature as she leaped 10 feet into the air to whack him with her club.

John then began to realise something.

"I know the possessed woman herself was a scumbag but what did the Oni itself do wrong?" he asked.

"Are you serious? She's an Oni" said Sophia.

John sliced the Oni's belly only for the gash to heal. The Oni whacked him with her club, sending him flying. John used aran behind the creature and stabbed her in the back. However the Oni was not defeated yet. John tried to a new strategy, seduce the Oni.

He used a lot of arousal on it. The Oni moaned loudly. John then placed the collar round her neck.

"What?" asked Sophia, "Onis don't surrender"
