I claim Ibaraki Kasen from Touhou Project as my waifu.
Even until now, she remains a mystery, one charming mystery that is. Despite of her serious demeanor, she is actually a fun-loving person as long as this fun doesn't violate anything. Eager to learn new things, unshakeable determination, and doesn't hesitate to do things that she considers right and proper, are some of many admirable traits for me.
