For those interested a
nd impatient like me good news! Seems vol 7 will be released in early autumn.
DMI’s twitter (23 Mar):
“Iiit's official, Ai no Kusabi vol. 7 and Only the Ring Finger Knows vol. 5 will be released at the end of August”
With this I presume release Book Depository and Amazon announced on their site - Sep. 11th is probably correct one.

“We'll be restocking the earlier volumes beginning in June so everyone can be caught up and prepared for the August release!”
