Innocent eyes like Kokoa's can't unsee unless there's something brewing in her young mind.
But non the less Gin is your typical pervert friend that likes to take advantage on girls and yet still be on your side. BUT STILL A PERV.
As for the chairman and bus driver. I think these guts with flashlight eyes seems to be the ones that have control over the academy. Also I think the bus driver also is the strongest, unless the 3rd flashlight eye authority appears. Also noting not what chapter when seeing Youkai academy sealed from a barrier are 3 persons. 1 of them could be the bus driver since they have that white cult mantue over there heads so we can't distinguish them from one another. Also I think these 3 have assigned themselves for certain purposes for the academy, one as the chairman one as the bus driver the other ???.
