User blog comment:Monkey.D.Me/League of Red Stuff .. no, its not KoolAid/@comment-4904935-20120504054514

O__O Are you kidding me???? I can't believe you made a blog out of the information like that!

Hummm...I wonder what is next from the greatest MDM-sama!?!?!?

Okay so, my blood type is S (O positive), which means I share mine with Robin and Usopp :P

BTW, my mom is right here in California, and NO, I didn't need to ask her about my blood type since I have donated blood for my family member, and couple of times in high school for Redcross:) so I already knew about it!

P.S. I got this information from OP volume 66. Per Oda, mainly there are four blood types: X (A), F (B), XF (AB) and S (O)
