IIRC I've seen a couple more of his work in G-men, could be wrong though. But yeah the Otoko Matsuri series does feature him. Quite a good manga segment if I may add.>the novel's price is increased from 324 JPY to 756 JPY (DLSite)
What are you even talking about?
The novel is available at 3 stores for 3 different prices (721Y, 756Y, 600Y)
The author doesn't have to remind you about anything.
The description tells you that there are 38p and there's already 3 cut-in illustrations as samples.
You should remind yourself that you are buying a novel, something to read. And not something for pretty pictures.
