Shinsengumi Mokuhiroku Wasurenagusa
Rejet is working on something new: 新撰組黙秘録勿忘草 (Shinsengumi Mokuhiroku Wasurengusa, Shinesengumi Secret Files Forget-me-not, after this simply Wasurenagusa) is a series of situation CD's based on the Shinsengumi and the concept "what if I could have been there". The series will use the Dummy Head Mic.
With each CD comes a ticket, if you buy all 6 you can apply for a special drama CD which has all of the characters interacting with each other. So far this seems to be a drama CD only series, but you never know what Rejet has planned for us...
The cast for Ojisama Senka vol. 5 and 6 have been announced. Vol.5 will have Genda Tesshou, Hamada Kenji, and Tobita Nobuo. Vol.6 will have Ishizuka Unshou, Ebara Masashi, and Touichi Hiroki. The titles for both vol aren't final yet, but for now they are titled "itsumo no tokoro de" and "escape".
When the cast for vol.5 was announced it first said that it would be Hayami Shou instead of Tobita Nobuo, but one day later an apology saying that this was false. Tobita Nobuo was announced as cast one day after that. The apology mentions "a confirmation mistake on behalf of [his] agency" as the reason why he can no longer participate.
A mobile game on Gree has also been released, but unfortunately I have no further info on that.
Seems like the Versus CD's won't be the only thing to be released this summer: A limited edition drama CD is planned for the Summer Comiket. The contents will be about the heroine going to the beach with all of the Sakamaki brothers. I'm having some problems imagining some of them on the beach and what the situation is going to be like though.
There are rumours on 2ch and twitter about a Kareshi Igai 4, but I haven't been able to find any official news on it yet. According to the info there vol.4 will have you cheating on your current boyfriend with your ex (CV: Miki Shinichirou), but we'll have to wait until it pops up on the official site or a webshop somewhere before the rumour can be confirmed.
Also on the Cineria site: a web CM for Sleep x2 vol.2 has been released. The CM itself almost makes me sleepy so I expect the actual CD to be quite effective again.
Another Seiyuu has been tricked into acting like a cat: this time it is Masuda Toshiki. The CD is planned for a 2012.08.08 release.
Aroma na Kareshi
sample track you first meet him when visiting the salon where he works. He is described as looking cute, but being surprisingly capable and a hard worker. He also loves pretty hair, and has a bit of a hair fetish. the release is planned for August 2012.
Otenki Sentai How Weather
The Weather Sentai series continues with Vol.4, which will be all about summer and a summer camp. Other than that the theme is going to be summer, and that it will feature all previous characters I know little about it though. I expect them to go to the beach somewhere along the way though.
Ouritsu Ouji Gakuen
The third series of drama CD's in the Ouji Gakuen series have been officially confirmed. This season features three first year students: Vol.7 will have Aladdin (CV: Midorikawa Hikaru), Vol.8 the Prince from the Swan Lake (CV: Ishida Akira) and Vol.9 the Frog Prince (CV: Suzumura Kenichi). The release date for Vol.7 has also been announced: 2012.09.15. Unfortunately there are no character descriptions or designs yet...
While browsing the official site I discovered something that I completely missed before, but Double Score will be using the dummy head mic. Each CD will be about 50min, and about half of that will be done with the dummy mic, although there are apparently situations in where the dummy head mic is used but you are not present (like when you hear someone's thoughts maybe?) and that "a certain CD released in November" will be almost completely dummy head mic (I'm guessing Chisato his CD?). The subcharacter will feature in the CD for about 2/3 to half of the time.
With the first CD released, you can grab a limited time wallpaper over at the official site as well. It will be up until 2012.06.28 (when it will most likely be replaced with the next one).
About a week ago the official site updated with a promo movie for the second Kindan Kyuuketsuki CD. Shimono Hiro his partly innocent, partly mischievous voice is, errrr, quite effective? Ok fine I'll admit, I am sold. I'm still not entirely sure about the gratuitous German words though.
