Erik: No. Thanks for mentioning it now. ;-)

Oscelot: Most Japanese names are written with Chinese characters, and thus have obvious meanings. However, the same sound can be written with lots of different characters, and the same character can be read lots of different ways. Akiko's name is written with the characters for "bright" and "child", while Reiko's is written with "spirit" and "child". Another possible reading of the "spirit" character is "tama". So Akiko was trying to reconstruct Shiraishi's given name, and got the wrong reading.
