Spell her name as Jirou Kyouka.

After several failures, I finally figured this out after noticing that a post by barry915 featured this character. Sadly, that post has its prompts hidden. However, by searching tags, I discovered 2 other posts that listed Jiro with the forementioned spelling.

Sadly, I have yet to make any progress for Hagakure Toru.

UPDATE: I feel a bit stupid, but I realized that since the way to get an accurate Jiro is to spell her name with a more accurate transliteration of Japanese to English, the same may apply to Toru. Turns out, yes. Hagakure Tooru works.
