Asuna after having become a succubus.
She was the first victim of a succubus who came from the Demon Realm. Her love for the main character hasn't changed, and she's still overwhelmingly bright and cheerful.
For a succubus, she is obedient and easy to manipulate. She is extremely dedicated to pleasing the main character, and to that end, she'll do whatever it takes. In order to make him a harem, she's going around and sleeping with other girls close to the main character, turning them into succubi.
When she interacts with the main character, she becomes a pure masochist, and she's happy no matter what is done to her as long as he's the one doing it...
