Stellnova

Stellnova, also known by her real name in the world of the 7 Stars, Hinako Hoshizora, is a main antagonist in season 2 of Wish Upon The Pleiades.

Personality
Stellnova seems to be a very quiet, but very cunning girl, who can somehow predict the moves of others. She refuses to befriend or talk to any of the members of the Cosplay club, showing that she has a cold personality.

In the past, Hinako was a very honest, kind, and soft-spoken person.

History
In the beginning of episode 1 (in season 2) of Houkago No Pleiades, Stellnova is shown at the end of the episode, as she is coming up with a plan into taking away the fragments from the members of the Cosplay club.

Later in the episodes of season 2, Stellnova is revealed to be a villain, and just like Minato, her goal is to take away the fragments from the others, just for her own, somehow selfish, needs.

It isn't until episode 8, that she finds out that she was being brainwashed by her little sister, Arstella, the whole time.

Casual
Although Stellnova's casual form is never rarely shown, Stellnova has long, black hair

Transformed (as Stellnova)
When Stellnova is transformed, she has a black dress, with green and black tights, and wears black heels.

Special Items(s)
Stella-Nova Staff: Stellnova's main magical item that she always uses. The staff's magic can make Stellnova do anything, such as flying faster, capturing fragments faster, and having any sort of power.

History (Part 2)
When Hinako was not brainwashed by Alma in the past, Hinako was a very honest, kind, and soft-spoken person. Her parents seemed to pay more attention to Hinako than Alma, which caused Alma to get jealous, and ended up brainwashing Hinako into Stellnova.

Relationships
Arstella (Alma Hoshizora) - Arstella is Stellnova's younger sister, although Arstella shows a strong hatred towards Stellnova.

Queen Constella

Minato - Although Stellnova and Minato have never met each other, or barely speak to each other, they were somehow connected all along.

Himeru - Although Himeru and Stellnova barely speak to each other, Himeru was the first one to see Stellnova in her dreams, before the other members of the cosplay club did. Although, when Stellnova was able to return back to her normal self (in the OVA), she seemed to get along with Himeru the most.
