Blick Winkel

Blick Winkel (ブリックヴィンケル, Burikku Buinkeru) is a fourth-dimensional being in Ever17. They are in essence the Third Eye, the reader, and player of the game. "Blickwinkel" means "Point of view" in German.

Being a fourth-dimensional being, they can move freely on the time-axis. For this reason, they are tricked into believing the 2017 incident and the one occurring in 2034 were one and the same, luring them into the world of the game in order to save Takeshi Kuranari and Coco Yagami from IBF.

Ryogo Kaburaki
It is implied in the game and confirmed in the 2035 Drama CD that Ryogo Kaburaki lost his memory when Blick Winkel briefly borrowed his viewpoint. It is also implied Ryogo doesn't like them, but begrudgingly asks for their help again to save Sora.

Takeshi Kuranari
Takeshi's is one of the two main viewpoints Blick Winkel borrows during the events of Ever17. It's thanks to them that Takeshi is saved from IBF in 2017, then 2034.

Hokuto
Hokuto's is one of the two main viewpoints Blick Winkel borrows during the events of Ever17. They accompany Hokuto in saving Takeshi and Coco in IBF.

Yuubiseiharukana Tanaka
Blick Winkel speaks directly to Yuubiseiharukana Tanaka in multiple occasions: first in 2034 when they discover their identity, then in 2017. When they first tell You to rescue Takeshi and Coco, they soon realize that would cause a paradox in 2034. Blick Winkel then comes back to 2017 and tells You a plan to trick themselves into being lured into the world of Ever17.

Coco Yagami
Coco refers to Blick Winkel as Brother, and has romantic feelings for them. Despite this, as Blick Winkel is supposed to be the player, they're not necessarily of any gender in particular. Coco explicitly asks for Blick Winkel's help more than once, and it's thanks to them that she is saved from IBF in 2017, then 2034.

In the Epilogue, she is the first to notice Blick Winkel and to wave goodbye.
