This is the fourth and last captain of Kushal's horde. Tarun is a pine marten like Kushal himself, and is actually secretly Kushal's favorite captain (though everyone thinks that Senka is Kushal's favorite). Oddly, Kushal thinks of Tarun as a little brother, and often has talks with him in his tent.
Although Tarun is the youngest of Kushal's captains, he is actually very experienced, as can be seen by those scars. He is proficient in ax-wielding as well as a variety of other weapons.
One interesting thing about Tarun is that unlike the other captains, he dislikes needless cruelty. You can bet this comes into play in the story.
Interesting fact: even though I had a pretty good idea of how I wanted him to look, it wouldn't come out on paper, resulting him looking a bit awkward, but oh well, I can do another drawing later on.
