Finally up to speed after watching the anime weeks ago... Dad is a prick, after having named two of his children Haruka and Hikari decides to name a third one Hikaru, thankfully the last one didn't stick around.
So far Cocoa has:
1. Charmed Chino's grandfather to become a rabbit.
2. Contacted the ghost of Chino's mother.
3. Got access to a mirror world.
4. Opened a gate to a dystopic future.
While still trying to figure out how to be a reliable older sister.
They can't do safewords because it contradicts the basis of their relationship. She loves him because he understands her to the point of not needing to say words.
I'm glad the author found a way to give Suu a personality beyond her love for numbers. That is, being an overconfident dumbass.

Not gonna lie, I was expecting a The Truman Show reference once Rentarou reached the wall.
Lucoa's sister was always a character. It is the cornerstone of her current situation, the reason why she lives with Shouta and fears of losing him and the new family.
Megumi has no hints because she is the one. Trust me.
In all seriousness, I believe she is the one because Nadeshiko treats her the same way she deals with Sakurako. Nadeshiko is in love with someone resembling her clumsy sister.
I don't get this. If the point was to make Aki being involved in a love triangle with Shiho and her sister, and for the sake of the argument I'm assuming this makes sense, why introduce a new character?
Wouldn't had been easier I don't know... Showing us the damn scene in which Aki tells her...
