Hien

Hien is one of the supporting characters of the Ultimate Familiar story. He serves as a guide to Shadow in providing information of the land of Halkgenia around him.

Appearance
Hien is merely a small orange flame that burns on Shadow's chest soon after he was given his familiar runes from Tiffania. Due to being near Shadow when he provides spirit essences to his sword, Zenyōso. Hien changes color to match the element Shadow is using. It is worth noting that Hien can change color based on emotion as well auch as when Hien turned dark when Shadow succumbed to his dark form or when it glowed a pale gold when Tiffania was with him.

History
Prior to bonding with Shadow, Hien was wandering about the land of Halkegnia aimlessly. Upon stumbling Shadow being in the effects of the familiar contract, Hien was subsequently pulled in due to both the spell and Shadow's Chaos energy, causing them to be fused. Though both expressed surprise upon being alert of each other's presence, they both didn't mind and continued as if nothing happened.

Hien has acted as a source of info to Shadow during battle or in ancient historical sites. This made everyone trust the spirit, though his timing can be of concern.

Personality
Hien is a humble being, though it belies his rage when provoked. Initially, Hien was more happy-go-lucky, though he retained his knowledge of the past. It was a complete opposite of Shadow's former personality, which helped him lower his tension.

After the battle of Tarbes and stopping the invasion of Reconquista, Hien took a noticeably mature tone. He's known to speak with authority, often commanding those of Noble lineage to lower their arms, lest they incur his wrath, using Shadow as his avatar. Humans in turn, feared the spirit of fire, not wanting an outburst to occur.

Despite his volatile personality, Hien is known to be somewhat scatter brained. Despite his times in providing info, Shadow often comments how the spirit tends to inform him during a later time in battle (a running gag in the story). Despite the dangerous nature it shows, Shadow doesn't complain any further about the spirit's information, though he wishes Hien could inform prior to battle.
