Amazon link
With the amazon link you can zoom and see what it says on the cover, it says in english:
The comic that collects 12 stories about transforming into opposite sex.
and
CHANGE SEX.
CHANGE GENDER.
CHANGE XXX... etc
The amazon link also provides the back cover.
If this was going to continue it would have said
Vol. 1 on the cover... it seems to be an only 1 issue manga anthology, but its being published under a new comic imprint
TS Comics which might imply that further transsexual manga will be published under this imprint in the future.
