There will be vol3 yes!! I was so woried it would end now. Would have been a really good end though, but i need more !
Really highlight was this bonus with the m16 xD
So next Time yagami will lvl up to rin job , Who will take yagami place ... Aoba is still a newbie, hifumi is too shy, hajime would be a weird lead but i could see it work, but i would see yun fit the role the best
Remember that Yun actually in the animation department. She was just sitting with them as they don't have desk in the other block.
In that case, Hifumin probably will be the interesting choice, plot development-wise. A team leader who can control everything through chat, but not through face-to-face.
Not to mention she is sorta afraid of Aoba teasing her. So yeah hilarious could ensure
