Translation request at Panel 3 on the right side.
Searching 前衛的 anywhere give me "Avant-garde". And combining them all would be "Avant-garde Idol of the Mirror (Mochi)" to me.

Also, on panel 1. What's a "Monster Morning?" (that's what it literally read)

As it shouldn't be the big erection you get in the morning that doesn't go away, it must be the enormous meal you get for breakfast.

Specifically, it seems that a 'Monster Morning' (set) was is what enormous breakfast that the wrestler Makanishi Manabu eats is called.

Kagami Mochi is characterised by it's shape, which is probably being played on here.

Thanks as always, I though monster morning is some kind of greeting like 'good morning' here.

So that's actually means "avant garde"? I tried to search it and they say it's some kind of experimental/innovative art. So I guess it's something like "experimental mochi-like idol"?

Avant garde usually is used for art that 'ahead of the curve' so to speak - for example, Cubism could be called avant garde. Things that challenge the status quo.

Keep it together Jintsuu. Someone has to hold this family together.
