Hyena (Korean: 혜나, not pronounced like the animal, but as hye-na) is one of the main characters of the series. She is Dana's only sibling and younger sister.
She is a short girl with pink hair and red eyes. Her mother has the same color scheme as well as Dana. She is twelve-years-old and is in the fifth grade.
She is an enthusiastic, and headstrong girl with a bit of a sharp edge. At first glance, she seems very pure and naive. This is a front, hiding her devious and short-tempered side.
Unlike a child of her age, she is blunt and acts without hesitation. When she gets angry, she lets loose, similar to her sister, as shown when she repeatedly attacks Orca with a taser. She also uses the fact that she's a 'cute girl' to her advantage. This seems to be a result of watching Dana and Guineung from a young age.
She is also much braver than a lot of adults.
Despite this, she is a child and acts like one on multiple occasions. An example of this is when she became very upset when Naga left SPOON in Chapter 38, to the point of crying. She also tends to hug people she likes.
- Summoning: Hyena is a witch, which means she has made a pact with a demon. Her contracted demon is the Demon Lord, Solomon. She can summon any demon she wants by drawing a simple pentagram. Since she is too young to know all the different pentagrams, it seems that by drawing a simple pentagram she can summon any demon she wishes. Therefore she does not need to now the different pentagrams.
- Other: She can fly with a broomstick, which is why she's part of the Flight Team.
- Dana: As Dana's younger sister, Hyena is cared for as her sibling as she can be seen sleeping in Dana's lap. The two share a short temper although not acted upon each other, but rather upon Naga or Sasa. Dana and Hyena share a great age difference, but they have a great relationship as coworkers and family.
- Naga: A brother/sister and teammate like relation.
- Sasa: A brother/sister and teammate like relation.
- Hyena's ambition for the future is dominating the world.
