The first volume of Mizu Sahara's Tetsugaku Letra has been published and you can now buy it in japanese from amazon
here.
And apparently, as celebration she she gets to be on the cover of
Gessan again this month (2011 #11) and you can buy that issue
here.
Am I the only one dying to know what the shoes are all about?!?
Let's all hope that somebody will feel like scanlating it in the near future.
Thanks to
hsoyou for the info!
