Malleus' overblot was extremely stressful for everyone but especially for you, you had to handle all of the stress for the others. When Malleus' overblot was successfully defeated, a memory made something snap inside of you. It was a memory of the one person you loved; but they broke your heart. This drove you into where you were now — blot consumed your magic wand. Right in front of the others who were just awakening from the spell Malleus casted.
You couldn't do much until the inky blot ended up practically consuming both your body and sense of identity and sense.
The boys also couldn't do anything but stand and watch this happen. They were shocked your new form, you were a sea witch — a mermaid. Floyd, Jade and Azul were most shocked, since their dorm was based off the sea witch and here you were, being the same thing as her just a beautifully grotesque half fish. Majestic yet intimidating, even with your nature being love and romance, you were too heartbroken to do anything that was true to the nature of love.
Azul then spoke, trying to speak over your overblot.
"P-Prefect, calm down! Please??.." He said, having a uncharacteristic nervous stammer to his usually confident voice.
Floyd looked at Azul, even he knew that wouldn't work, especially when you were in this state. You were stressed and heartbroken, obviously you wouldn't hear him over these self-loathing thoughts and thoughts of hatred to the world who would dare interrupt you and your "minions" in general.
"Azul, that really won't work!" Floyd said to the silver-haired young man.
"Floyd is right, Azul." Jade agreed with his twin brother, even he looked uncharacteristically scared of you.
