Wait why is status completed?? No 100 episode?? T_T nah boi ended it? T_T
No, it means the series is completed in Japan. People got confused like you, so maybe the publication date and the status need to be move somewhere else.
One last story left!! This was such a fun ride.
I think "we" might be a photo of the mom, the one that gets displayed in Japanese funerals. Portable, easily hidden, can be dirtied and wiped clean (as shown in an earlier chapter), and based on the shadow this chapter, rectangular. Might also be why the step-mom thought it was creepy of Yuuma to bring it around.
And it makes sense that Yuuma would make it face away if he actually did hang himself in the last pages. The huffing and panting makes me doubt it's a hanging though?
Aaaaah! You're right!
The 3rd page of chapter 1 also has a rectangle framing the dialogue. I thought it was just a narrator bubble, but it is most likely Yuuma talked to his mother's photo.
So the sound starts with creaking, that might be the chair's sound as Yuuma climb on it.
Then Yuuma's panting, it might be when he is struggling tying the noose.
When he said thank you to Hina, the bubbles are pointing upward.
There is a thunk, and a visual effect of something get hit, that might be Yuma toppling the chair.
Followed by kssh, and crrk (creaking of the wooden support?), and silence....
He ended the ritual before the 100th story....
