Any idea that's unnecessary except for satisfying the author's own desires doesn't need to be included, especially when the next chapter is the finale. She already got to indulge those desires in Chapters 128–129 anyway.
That's why I've been posting repeatedly asking what exactly Katsura Airi wants from Grapara. It's not just that she doesn't understand what the readers want; she doesn't seem to know which characters she's writing, and she doesn't even seem to remember what she has written before, as if whatever personal desire is driving her has completely blinded her to the story.
Grapara could have ended with Shikura, Shifumi, Shichico, Shiryusei, Shiproducer, Shimio, or even Shi Shadowclones in Chico Lap no Jutsu all along. But Katsura Airi's apparent lack of understanding has pushed the series onto a disastrous path.
