@SuperOniichan The last letter in the hiragana alphabet is wo (を). wo is usually pronounced as a vowel (o) in modern Japanese, and is preserved in only one use, as a particle.
Basically it is written as を, which is also pronounced just like o (お).
I wonder if she got published with that lo/ this pair is awesome... But we gonna have to wait until graduation....maybe.
And I'm glad he got his udon right at the end, nice one author.
