Ikari no Hoshizora (怒りの星空) is an action platformer where the player selects and controls one of the 4 playable action heroines, Shiori Hoshi, Roxanne Starr, Anzu Shirogane, and Midori.
Its art style is reminiscent of 1990s anime such as the shoujo anime Sailor Moon, shonen anime Yu Yu Hakusho, comedy anime Slayers and Tenchi Muyo!, while its experimental themes rooted from Neon Genesis Evangelion, Ghost in the Shell, AKIRA, and Cowboy Bebop.
Shiori Hoshi (星 シオリ) is the leader of Team Hoshi. She currently owns a teahouse which acts as the team's residence.
Shiori was known to be one of the most intelligent bookworms during her college years on Earth.

Roxanne Starr (ロクサーヌ・スター) is Shiori's loyal junior and the team's brawler. She seems to be pretty snarky at times.

Midori (ミドリ) is the newbie member and hacker of the Nocturne, piloted by Nyx.
