"I think I have an idea," Riku said after a bit of silence, this was a bit to even think over. Lambdadelta just threw out the big guns for sure... "Oh really now? Humor me with what you have to say," she rolled her eyes, certain that her Red Truth was very solid and flawless. "Clarify this for me, just...what exactly is your definition of a perfect closed room?" Riku asked, wondering what she had in store as a response. "Well, it's pretty simple, *a perfect closed room must have a locked door and windows, that no one leaves through the door or windows, or even enter through until a key is used.* Is that all you needed? I do hate going off track from the topic," Lambdadelta said, using the Red Truth again to prove her point. Riku didn't say anything as he gave another moment to think, then he realized something. "Sounds like a tricky closed room then...though, I can see you have some loose bolts that Person B's disappearance is a perfect closed room, based on your definition. So, I'm taking as there's no ceiling to this room," Riku finally speaks his mind, seeing that the Witch definitely used her Red Truth in a poor manner to leave a flaw. Since she had already said it in red, there was no do-overs, it was like a double-edged blade, that Riku managed to flip the effects over to catch her in this pathetic mistake.

"I can tell that you're very genuine with this decision of yours, and that you have great potential in store. As there isn't any reasons to decline your requests, I will gladly take you as my Witch Apprentice," Virgilia smiled, knowing that Sora was not the kind of person to become corrupt with power like how Beatrice appears to be. "I'll help too! I'm still in training, but I can pitch in some way," Maria pipes up, she was still an Apprentice too, she would start training with them after what happened at their encounter with Beatrice.
