Reika is a top level gravure and “talent” idol always busy shooting TV commercials, doing appearances and basically never, ever stops working.
For the first time in months, she decided to take some time off and go shopping in Shinjuku, and on the way to a departments store from the east exit of the station, she wound up being another of the victims of the Shinjuku Massacre, shot to death by Izumi.
In actuality, Reika wasn’t particularly attracted to Kurono at the beginning; she as was teleported in by the GANTZ, and was stared at for, well, being an idol and famous person amongst normal folks; she had no choice but to go with the flow and follow Kurono as leader.
Heeding useful advice, Reika wears the GANTZ suit, and while, attempting to join the battle, was impressed by Kurono’s ability to carry on combat all-the-while not causing damage or harm to innocent bystanders.
It was then that she felt something for Kurono, as it’s not unnatural for a woman to be attracted to the strongest of the men.
Her feelings for Kurono developed, which might have started with Inaba, in a sense — Inaba was around Reika the whole time in the Kappe mission, and was all talk and no action.
On the other hand, Kurono is no talk and all action, so it’s natural that she was drawn to him and began to have feelings; unlike women, men are not human beings, but human doings.
During a live national broadcast, Reika accidentally mentioned that there’s someone that she’s interested in, and this caused a general idol-level scandal, making news on TV, the internet, general trash-rag tabloids, and everything in between.
However, she’s decidedly brave, gave Kurono a call, and decided to go out and see Kurono late at night. Right as they were about to part ways that evening, she wanted to confess her love for him, but suddenly got tense and was unable to do so.
Even though she’s a top idol, she’s still a normal girl deep down inside, and that part of her own out, her timidity getting the best of her and not allowing her to confess her feelings.
When it comes to love, the intuition of a woman cannot be beaten.
During the Ring Alien mission, Reika accidentally ran into Tae Kojima on the battlefield.
Merely by looking at the behavior of Tae around Kurono, she could easily tell that she was his girlfriend. Even amongst the savage world of GANTZ, the loves and lives of people intersect with one another.
--- Oku-sensei’s comment:
Since Tae-chan is a little plain and average as a heroine, I put Reika in the story so that there’d be a sort of triangle involving a couple normal people and an above-life, super idol.
Naturally, the name Reika is a stage name, and her real name unknown.
Reika wasn’t modeled off of anyone in particular, but she’s simply a “top model that appears in TV commericals.” If I were pressed to pick a model, it might be Sumire Hoshino of the manga/anime “Perman.” (laughs).
