僕は思うんですよ。
この「乳」はおっぱいの「乳」ではなく「鍾乳石」の「乳」ではないかと。
「初音」は主に春先の、うぐいすの鳴き声のことを言うらしいんですけどね。
つまり「初音乳」とはうぐいすのう(回線が切断されました)

コミケ2日目に当スペースにいらしてくださった方、ありがとうございました。
めちゃくちゃ大混雑してたりブース内もてんやわんやしてたりと、一時はどうなるかと思いましたが、なんとか無事終わりました。
3日目行かれる方は頑張ってください！
ぼくは用事があって3日目は行けないのでした(^^;)

Here's what I think: This "breast" kanji isn't as in "boobs", but as in "鍾乳石" or "stalactite". Apparently, "hatsune" mainly means the call of the uguisu, the nightingale, at the start of spring. So in short, the "Hatsune breast" means the nightingale's n&#(*$%((#*NO CARRIER

Thank you very much to everyone kind enough to come by my space on the second day of Comiket. It was ridiculously crowded and hectic even inside the booth, so I briefly wondered how things would work out, but somehow, it all ended safe and sound.

Everyone who's going on the third day, please hang in there! I have some business to attend to, so I couldn't go on the third day. (^^;)
