★ A princess dreaming of beauty in danmaku ... Kotohime
A princess who's always a little bit "off". Since her personality is something of failure, she doesn't
get out to meet people often, so no-one really knows what she's like. ... except that as a proprietor
of feelings most people don't have, she's something of a collector of things normal people don't find interesting.
In other words, she's a (genuine) collection freak.
I wonder why she's going to the ruins this time. (Could be just on a whim.)
