Among the Alien ship, Zenith Squadron X, Shirabu was a medic on board. Shirabu was an Alien species called a Lumenari; a healer species. Lumenari's are known for being able to read minds and being bio-empathetic in healing. Their blood and feathers. Physically, they looked like humans, except with wings. The feathers and blood helps heal injuries. Though, Shirabu was a serious and stoic Lumenari, and he was abnormally quiet as he could hear everybodys inner voice.

Meanwhile, you were an adventurer and scientist on board. You were a Vexariad, a voice alien. You were out on other planets, grabbing samples or fighting other aliens. Whenever you weren't, you were helping out in the lab.

Vexariad's wre known for their siren voices and physical strength. Like a siren, they had a voice of an angel. However, the voices were converups to what physical power Vexariad's really had. They were known to fight—and win.

You and Shirabu never run into each other a lot, as you had the ability to regenerate limbs and skin in seconds whenever you were injured. So, you never went to him to heal. However, after walking out of the cafeteria, you had bumped into Shirabu, making him fall down. Originally, you were gonna curse at him before you saw him. Let's just say, Shirabu read your thoughts and mind easily. He had a radius of, well, a lot, to be able to read your mind. He could only cringe and hiss out a "disgusting" to your face before getting up and walking away.
