He later became the siblings' underling after the Werebeasts lost everything in the Eastern Union to them. He is protective of his granddaughter and becomes unhappy and jealous whenever she is close to the siblings. According to "Miko", he has thirty wives, much to Sora's chagrin. He was possibly one of the participants of the games between Imanity's ex-king and the Werebeasts.
He is described as a white figure due to his long white hair (tied into a ponytail sometimes), tail and ears. Despite his old age, he has a very muscular body "like Schwarzy's in his prime" with enormous muscles that show through his kimono. He is often seen wearing his kimono and round glasses although when it comes to beach/bathing attire, he switches to a red loincloth but keeps his glasses.
He acts in a rather formal manner around guests and officials. However, when around rude or condescending people, he tends to reciprocate their attitudes back despite their diplomatic rank.
He expresses a caring attitude for those he knows, especially his granddaughter, even though his outer expression may suggest otherwise.
When not during his jobs, he speaks many dirty jokes.
It is revealed that he is a very loyal devotee to Miko but also a perverted person with around 30 wives. He opposes the civil war between Werebeasts because he wants to have sex with women from all tribes (he was banished because he did it with all of his tribeswomen.). The reason Ino became her right-hand man was his hidden feelings toward his madam (and a deal to make Polygyny legal in Eastern Union).
He has all typical Werebeast physical abilities, including magical sensory, extreme vision, sensitivity to sound, extreme strength, and extreme speed, to name a few. He is also one of the Blood Destruction-capable individuals, although he could no longer withstand the stress of using it due to this age.
Besides physical capabilities, he is also a very skilled politician, as shown when he assisted Stephanie Dola in ironing out all the complex work necessary for a multi-racial nation to function.
As seen in the anime, he is very doubtful of Sora's plans that even Izuna figured it out before him. He has a soft spot for Izuna that can be exploited in certain circumstances. The biggest weakness that he has is underestimating different races especially Imanity. Instead of erasing the memory of Makoto Dola, they let him continue to have his memories that ultimately led to their loss after Sora had acquired the sufficient information that the previous king had written in the hidden chamber. It can also be seen that he is dependent on their technology especially video games in order to win games from other races.
- The light novels mention that Ino and Steph-kou have a bond, as they are both victims of Sora's manipulation.
- Steph-kou is a joke, as Ino pointed out Stephanie is Stephanie-kou or Duchess, and Izuna abbreviated it to Steph-kou.
- A running gag throughout the story is that his muscles gross out anyone that sees them. Not even the supposedly logical Ex-Machina are immune to this.
