This is Fire. Don't worry, I didn't see any mistakes at all. I loved the story. It was funny! And yes, it is fukutaichou although it can also be spelled fukutaishou with a "sh" instead of a "ch" depending on which romanji you're using. They are a little OOC but I'm sure you already noticed that, but you've done a good job capturing their personality so it's not too bad. Write more!

pardon me sayin tis. but.. i find renji is slightly OOC... but nevertheless, tis one shot is well written. keep up de good job.

that's cute =) keep up the good work! ^^

haha, nice story, hope you can come up with more. ;)
