OOC: Yep, they're one and the same. Speaking of which, I have a couple fun facts about Hanatarou.

Hanatarō's name is actually a play on the name Yamada Tarō, the Japanese equivalent of John Doe, and Yamada Hanako, the Japanese equivalent of Jane Doe. By combining elements from both, Tite Kubo is probably saying Hanatarō is literally a complete nobody.
Hanatarō's birthday is even on April Fools' Day, so people spend the whole day tricking him as a result.
Rakoua = Hanatarou = XD

Before the vehicle could crash, however, Kaze brought it in for a landing. Kenji stood there to greet them. "Yare, yare. You guys really have to go crazy when I'm not around. What's wrong with you two?"
Kaze chuckled. "Sometimes I wonder that myself." He tossed the unconscious Rakoua to Keiko with a wink. "You know what to do."
Keiko laughed. "Hai!" She dragged Rakoua inside. He walked out on his own feet about five minutes later. He wore a paper bag over his head. Kenji had to be a jerk and pulled it off.
Rakoua looked somewhat
like this. He had a bit of anger in his voice when he said, "Dont. Say. ANYTHING."
Kenji and Kaze couldn't help but laugh.
