DBDR-002: Ayaka Muto ur termalen ostatu batean infiltratzen da, non ingeniaritza zibileko langileak Yamanashiko prefekturako mendietan luzaroan ostatu hartzen duten! Bikaina al da ingeniaritza zibileko langileak asetzea, hain kementsuak baitira, non beren erekzioak ez baitira gutxitzen beren teknika harroekin jaurtitzean?
