Here's Tenma's little sweet pet, Astro~!

He enjoys staying close to Tenma when he is able to. He even trips Tenma sometimes by getting under his feet ^^; Even though there are a lot of accidents, Tenma loves Astro and makes sure that he is well taken care of and happy. Astro has a little mask he wears as an accessory, possibly fantasizing about being a superhero when he is out exploring.

I adopted Astro from the lovely artist  enlus They have very lovely work, make sure to check them out! :)
