Yup, only one English manga, unless Chuang Yi adds another title between now and Tuesday. Dem pickin's are a LOT less slimmer on the simplified Chinese side: you get Naruto 55, D. GRAY MAN 21, Bleach 49 and Majeh 35.

In Aphorism 6 (ISBN: 978-981-4341-52-3) —
Tomonaga's reign comes to an unexpected end and Rokudo is back to life, but the questionable actions of his alter ego have now casted suspicion and distrust among his friends. Is Rokudo's seal an extension of himself, or something else altogether? With the summer term upon them, the students must now rally themselves against the one called ‘Kami’, the founder and chairman of Naraka High!
–Chuang Yi's synopsis
Chuang Yi also publishes the simplified Chinese Aphorism (杀戮箴言) but that edition is still stuck at #4.
