OVA
Description
Azaka is a fictional character from the anime Tenchi Muyo! Ryo-Ohki, serving as one of the two robotic guardians belonging to Princess Ayeka Masaki Jurai of the planet Jurai. In physical appearance, Azaka and his partner Kamidake are unique, resembling floating logs or pillars. Azaka is distinguished by his name written in blue Juraian script on his body and features a purple eye on his front that functions as both a sensory organ and an energy weapon. Small logs are arranged around his base, allowing him to rest on the ground or hover in place.

As a guardian, Azaka's background is tied directly to his function as a protector and servant of Princess Ayeka. He is a construct designed for this role, though his powers are notably less formidable than the abilities of the Royal Trees of Jurai, which are the ultimate power source of the Juraian royal family. In the Tenchi Muyo! Ryo-Ohki continuity, Azaka and Kamidake are presented as early versions of Guardian Systems, which would later be developed into more advanced forms in other series.

The personality of Azaka is largely understated, as he and Kamidake are often seen conversing with each other while stationed outside the Masaki household. In the English dub, Azaka is given a deeper voice than Kamidake, conveying the impression that he is the older and more senior of the two companions. Their motivations are straightforward and unwavering: to serve Ayeka, follow her orders, and ensure her protection from any threat. They are capable of performing a variety of tasks beyond combat, including capturing criminals, drying laundry, babysitting, and even scaring paperboys.

Within the story of Tenchi Muyo! Ryo-Ohki, Azaka plays a minor but recurring role. He and Kamidake spend most of their time stationary outside the Masaki family home, where they are frequently seen but rarely active in major plot events. They act as guardians for Ayeka, generating barriers to protect her from danger and paralyze targets when necessary. By the third OVA series, their lack of mobility and prolonged inactivity leads to them growing moss and seedlings on their surfaces, emphasizing their passive role during long periods of peace.

The key relationship for Azaka is, first and foremost, with Princess Ayeka, whom he is sworn to serve and protect. He also shares an inseparable bond with his counterpart, Kamidake, as the two are almost always seen together and function as a pair. Their relationship is that of equals and partners, working in tandem to carry out their duties. In the household, they have limited interaction with other characters such as Tenchi Masaki and the rest of the cast, often serving as silent observers or obstacles.

Development for Azaka in the Ryo-Ohki OVA series is minimal, as he remains a static character. He does not undergo significant change or growth, maintaining his role as a reliable but background fixture. His most notable change is physical, as depicted in the third OVA when he begins to accumulate moss due to disuse. This contrasts with other continuities, such as Tenchi Universe, where the characters of Azaka and Kamidake experience resurrection and more dramatic narrative arcs, but those events are not part of the Ryo-Ohki storyline.

Regarding notable abilities, Azaka can generate powerful protective barriers that shield Ayeka from harm. He also possesses the capacity to fire energy beams from the eye-like sensor on his front, which serves as an offensive weapon. In addition to these combat functions, he is capable of hovering and moving through the air, as well as performing a variety of domestic and menial tasks as needed by his mistress. Despite these capabilities, his powers are consistently described as limited compared to the might of Jurai's Royal Trees and other more powerful entities in the series.
