Please add at least one full line to both the appearance and personality sections, so they're each 4+ lines. A few things to think about might be skin appearance and hue, along with eye color and any other notable traits. In personality you might want to consider adding Jun's view on humans/the world.
Also, why did Jun suddenly wake up one day and want to travel the world? He seemed pretty content living in Ryugu for so long, and was pretty successful doing it. Why was he willing to leave all that, just explore other places? Add a bit more about that in the history, please.
