Nope, I can't come up with a clever way to make this work in translation right now...
Spin...?Potter's...Spinning a potter's wheel...?Akashi is spinning that potter's wheel with her undivided attention!!She's expressing the 6th Anniversary of Kancolle, isn't she!Potter's wheel /rokuro/, spin = /mawasu/;
6th Anniversary = /roku-shuu nen/.
The pun here is that the 周 /shuu/ of 6周 can also be read as /mawasu/ when used as a seperate verb. Hence /rokurou mawasu/ = /rokurou mawasu/ > /roku shuu/Ah! That's a "I'm so relieved that it got through" face!!I got it!!I wonder?Did she get hooked on ceramics or something...?Congratulations!Ah!!
