Insert E. Is there any?
Is it a Japanese word spelt in English?
Is it someone's name?
Is it more important to find out what the word is rather than what the rooms exactly were?
Is this person a resident of Gensokyo?
Gah. Gensokyo resident, eight letters, with a number in it.Is the word Yagokoro?
Is it a first name?
A surname?
Two names?
Is the number hidden in the name in English (One, Two, Three) or Japanese (Ichi, Ni, San)?
Is the number hidden within the name in a well-known language?
Is the language European?
Is it African?
But you said we were spelling out a name and a number!
Is the language French? Italian? German? Spanish? Latin?
Does this riddle expect us to understand a European language that isn't English?
Is knowledge of the language this number is in necessary to solve the riddle?
So basically the number lead is useless, and we're back to 'a word consisting of a Touhou character + a number in a language no-one here knows'?
You mentioned earlier that the letter E was present. Was it in the number segment?
Is the number less than six?
Does the number have exactly four letters when spelt?
Therefore the number is one.
So am I right in thinking we're looking for an 8-letter word consisting of a Touhou character's name followed by the letters 'one'?
Or is it an anagram?
Does this combination proceed to spell a full English word?
Is the character in question from the Windows games?
So wait, it's going to be a jumbled mess? Like RUMIAONE? (If that's a horribly misspelt attempt to write Room I Own I will shoot you myself.)
