WN/Dino

Demon Lord Dino, known as the Wandering King and the King of the Sleeping Forest. He was given the rank of "Four Fiends of the Heaven Commanders" by Yuuki.

Personality
He is particularly bad at careful planning. He is also shown to be quite lazy and keeps a sleepy face all the time. Dino's pride, who is originally lazy in nature, only surfaces when he becomes truly angry. It is a rule for Dino is to achieve the biggest result with as little effort as possible. Therefore, avoiding the use of abilities that consume energy needlessly, but he'll use them if the situation calls for it.

Appearance
He is a slovenly green-haired delicate man. His appearance is no different than that of a human. Though he is a handsome man, his sleepy gaze ruins his appeal.

Chronology
To Be Added.

Background
Dino was Veldanava's most trusted retainer and remained by his side through every battle. He became the world strongest swordsman but after world peace was attained he was sent down to the world to observe and to be the surface's guardian.

After Dino Degenerated and became a Fallen Angel, Garcia and Pico decided to do the same. Before they Fell neither of them had an ego but one day they were suddenly able to think for themselves. They awakened an ego at roughly the same time.

As if Veldanava was awaiting Dino's absence he and his wife Lucia perished. Distraught from the news, Dino destroyed the whole country that brought this about and thought of destroying the entirety of the world but changed his decision after noticing an orphaned Milim. His entire reason for living was to protect her.

No matter how much time it took Dino felt that their master would one day return. Then suddenly one day he felt a soul that emitted the same brightness as his master. With his master still unable to move until certain conditions were meet he was told to remain as an Observer and to hide amongst the Demon Lords, the ones that posed the highest risk to the Angels and Seraphim. He was also told to listen to Yuuki, the child in which Dino's master inhabited.

Clash of the Dragon and Demon Arc
During the ensuing battle between the dragons, the Empire, and Rimuru, Dino was tasked with eliminating Ramiris. Dino didn't want to kill Ramiris but she or that of the Labyrinth posed a great danger to Yuuki and co.

Using Fallen Hypno he put everyone to sleep in the Labyrinth except for Shinji, Beretta, and Ramiris. He then attacked Ramiris as she approached him. He was subsequently stopped by Beretta, then Adalman and Albert, and finally by Zegion. He was peeved by the strength of all individuals in the Labyrinth and that it took three separate fights to figure out that he as the Observer was being observed the whole time he was in Tempest Country. He did feel bad about killing his benefactor, Ramiris, and thus intended to seal her with Deep Hypno (Eternal Sleep) but he failed.

Veldanava
Dino considers him as his Master and God since he is one of Veldanava's Creations.

Dagrule
Dino and Dagrule seem to be friends with each other as Dagrule allowed Dino into his place for a long period of time, though at the same time. Dino is also slowly depraving Dagruel to acquire him as a subordinate. Dino is nearly finished with depraving Dagruel. Then, Dagruel would retire, and it would become what Dino had planned. However, he did this just in order to release Dagruel from his bound to Veldanava for almost 300 years. Currently, Dino claimed to be kicked out of Dagruel's domain.

Karion
They were considered to be good friends.

Ramiris
They look close. Because a long time ago Dino was in her care, so he addresses her politely. Currently, Dino served as Ramiris's assistant in helping her research. Later on, it was revealed that he was observing her. He tried to kill her but the attempt failed and Dino fled. Even though he said his intention was to kill her he planned to put her to sleep as he still felt indebted to her. Afterwards, it turns out Yuki was controlling him through his light magic and when he got his senses back they became friends again.

Guy Crimson
After leaving Dagrule, Dino came to Guy's place to laze off but Guy told him to go to Tempest and tell Rimuru to take care of him instead.

Rimuru Tempest
Thanks to Guy's request, Dino came under Rimuru's employment as Ramiris's assistant. Dino seems to think of Rimuru as the most cunning out of the current Octagram.

Pico
He cherished her as his comrade and she is willing to follow him rather than Velda.

Gracia
He cherished her as his comrade and she is willing to follow him rather than Velda.

Celestial Demons
They are Dino's subordinates after the war (stated in the epilogue).

Abilities
Dino normally fights with a greatsword called Crumbling Fang. As he has no techniques for using a great sword his swordsmanship with it is based on his physical strength only. Using his two God tier swords, Excalibur and Caliburn, however, lets him easily rank as the greatest swordsman of the world. However, he only uses the two swords in his serious mode, which is such a rare occurrence that it often takes several millennia between two such events.

As a Fallen Angel, he is considered as a Light type spirit who shifted into a Dark-type variant spirit using several secret techniques of Ramiris. Therefore, the weakness against the Light attribute normal Darkness spirits have is negated through his familiarity with the Light attribute.
