Yeah...Kurumi was only mildly familiar with this part of Hogwarts' history, having sort of skimmed that section of the text. Reading such things late at night often left her with nightmares and needing to snuggle with a pillow. Yeah, some Gryffindor she was at times...

But now conversation had moved on to the Hogwarts Express itself. Kurumi's first spell notion was the same as what West had already voiced, so her hand stayed down for a moment until Vivi spoke again - mentioning the color of the train - and then her hand went back up. "Perhaps the color itself, the crimson, it a sort of enchantment? I mean...the paint. Sort of like what we use in Ancient Runes when we stain runes using red ochre. Could have been a magical activating agent," she mused. Then again, the whole paint on runes could also have been blood...and that just got her thinking rather morbid thoughts that sent a shiver down her spine.
