such an educational chapter. and makes me feel bad for only reading doujins exclusively with online scans (never had the money to go to conventions... would like to change that one day)
the mangaka is a very prolific Touhou doujin artist btw, so that's what the editor means in the behind the scenes there. it's like he created this manga just so he could eventually make this chapter at one point, lmao
one thing that bothers me - why won't Akina just say she's Umino Zaki? she even says herself that's not really information that would undermine her. and since Umino is a relatively well known Kanade fic authour at this point, it'll make their circle more notable too. like... you are actively screwing over the success of your booth here
