ooh ooh
a kiss x sis one shot manga appeared in
Weekly Young Magazine in issue 11, which was released on February 9, 2008
So now we have to look forward for chapter 14 and this one shot's scanlation >.<
ahh, be aware that Weekly Young Magazine is not Bessatsu Young Magazine, one is obviously published weekly while the other is published bi-monthly (the one that's unfortunately serializing the kiss x sis manga >.<).
