Apparently ordering this issue via Mail Order gets you a mat.
Specifically you get to choose from 3 different mats.
- “Planet Cray Stories” Version
- “Gyugyuttomorin” Version (A mat related to Mimori Suzuko, voice actress of Sherlock Shellingford, as well as Kourin from Vanguard)
- “Makeruna!! Aku no Gundan!” Version (まけるな!!あくのぐんだん！, A comic that runs in Monthly Bushroad. Non Vanguard related.)
