Luca Esposito

Luca Esposito is a member of Group B-5.

Appearance
Luca has pale skin with indigo shoulder length hair and grey eyes. His spacesuit is mostly neon green and blue with yellow outlines on it.

Personality
Luca claims to not like kids when he questioned why a 10 year old girl was joining the group. He's also a very curious person as he would walk up to something that catches his eyes despite not knowing what it is.

Plot
In 2063 A.D., Luca gathers at Mousanish Spaceport along with the other members of Group B-5 except for Aries Spring and Kanata Hoshijima, the former who joins them shortly afterwards and introduces herself. The teacher then introduces Quitterie Raffaelli and her younger sister Funicia Raffaelli who will be joining them as part of a unique task to take care of and teach a younger child. However, Luca voices his objection and says he does not like kids. Funicia then takes out her puppet and begins to badmouth him much to his surprise. Once Kanata has finally arrived, the group then boards their spaceship to begin their four hour journey to Planet McPa. Upon landing, they exit the spaceship and walk around for a bit when Luca points out a strange globe that's been approaching them, calling the group's attention to it. He walks up to and touches it only to get sucked in by it and sent into outer space.

They are able to find a nearby spaceship and upon collecting their luggage, are able to board it safely. When Kanata asks if everyone is here and if they're hurt, Zack Walker says that there is one person missing. Ulgar Zweig looks outside and sees that Aries is still floating outside, with her thrusters and communications unable to work. Kanata volunteers to go out and rescue Aries while the rest of the group watch over the cord tying him to the ship. He is able to successfully grab Aries and bring her back to the ship where she thanks him repeatedly. As the group wonders how they can get out of their situation, Zack is working on the ship's coordinates and finds some disturbing information. He says that they are no longer above Plane McPa and that they are 5,012 light-years away from their original location. The group could do nothing but react with shock at this news.

On the third planet, he reveals to Ulgar that he is the son of the politician Marco Esposito, and he reacts with shock. Later, Ulgar threatens to kill Luca with a gun, in order to pay back Marco Esposito for killing his beloved older brother. Luca reveals to Ulgar that his father doesn't love him, because Luca is both intersex and adopted. Ulgar then gives up trying to kill Luca, but a giant tidal wave comes crashing in and sweeps them away. Luca tries to hold on to Ulgar to prevent him from drowning, but Ulgar tries to get him to let go. Luckily, they are found by the other members of the ship and rescued.

When they get back on the ship, Ulgar apologizes to Luca, who teases him.

Art skills
Luca has a wide variety of miscellaneous skills that are useful on the ship. He drew the map of the Astra, cuts everyone's hair, and fixed a hair clip for Funicia.

Ulgar Zweig
They seem to be good friends, with Luca liking to tease him.
