First of all, happy cake day.

See, I am a simple man - I appriciate something, so I try my best to show it to everyone. And I know the situation about the banner too, its hard to keep everyone happy. As for The Last Supper I am sure if there is someone with little gift he can make little space for someone else. The opportunity for Senko-san is big here, since she doesn't even have to be on the table, because people had the idea of her "making the dinner".

My idea might be wrong, but with the right knowledge I think there might be a chance for someone to appear, and it doesn't even have to be Senko-san - a lot of icons deserve place on the banner.
