Shinohara

Shinohara (シノハラ, Shinohara) is the Warrior leader and creator of the well-known Orion clan. He is one of the most important volunteer soldiers and was the one keeping the corps together after the fall of Alterna. He also later acted as their representative to Jin Mogis.

However, Shinohara's true, loyalty is to Ainrand Leslie, one of the five princes and the one behind the volunteer soldier amnesia.

As such, it seems like his role as a representative was, at least in part, a cover to ascertain the value of and communicate with Jin on behalf of Leslie. And not long after Jin strikes a deal with the Goblin, an alliance he likely helped to forge, he starts to work under him as a member of the new Frontier Army.

Personality
He possesses a calm composure and is well-mannered. He is trustworthy and reliable as he's helped Haruhiro's team in understanding Merry's initial well-being. Though he firmly believes that people should learn on their own even for newcomers, he is willing to give advice on important things in life.

However, that outward reliable and polite personality is but a facade, and far from a perfect one. Shinohara's true personality is apathetic, he doesn't seem like he cares much for anyone around him be they the one he manipulates or the one he works for. A relic sword that was likely offered to him by Leslie, but whose powers are still unknown.

Level. 6 Towards a Glory Not Worth Taking
Shinohara was mentioned as the one who discovered that the white giants of the Dusk Realm had valuable metal called rainbow pyroxene.

Abilities
While, so far we've never seen Shinohara fight, from every account he is a powerful warrior, on par with Max from Iron knuckles, Ducky from the Berserkers, and Kajiko from the Wild angels.

However, he seems to be no match for Soma and likely Akira. Something he admits to Leslie, saying that while he can somewhat control the volunteer soldiers, he has no sway on those 2 and their parties.

From the fact that he wears full metal armor and uses a shield, it seems like Shinohara acts mostly as a tank.

Beheader
A smallish longsword used by Shinohara. From the way it's described it seems like its appearance is rather bland, however, that sword is a relic sharp and sturdy enough to cut a tombstone. Considering who he is working for, it's very likely that that sword was offered to him by Leslie, as he seems to do with those working under him. Moreover, has a relic, it likely has more powers than just being a sturdy sword with a good edge.

Soft power
While Shinohara is a great warrior, it could be argued that fighting isn't where he truly shines, as his greatest asset seems to be his skill at intelligence gathering and manipulation. Shinohara shows time and time again that nothing happening around Alterna really escape him and that he seemingly knows the situation of almost all volunteer soldiers even the less famous ones like Kuzaku in volume 4. Moreover, we later learn that he was in contact with the margrave of Alterna, showing that his intelligence network likely wasn't limited to the volunteer soldier corps. He is also a master manipulator, able to constantly play the role of the well-mannered clan leader, only rarely showing a glimpse of his true nature.

Finally, he is also a great leader, his clan being known as one of the most powerful, yet serious, something which can't really be said of most other powerful clans. The fact that he was able to control the remnant of the famously unruly volunteer army after the fall of Alterna, only reinforcing how talented he is as a leader.
