Nada

Nada (ナダ) is Master Red's former apprentice from the Ryusoul Tribe and later on revealed to be the current user of the Gaisoulg armor.

After the purification of Gaisoulg armor, Nada later joins the Ryusoulgers as their ally.

Character History
Apprenticed at some point by Master Red, Nada originally thought of Ryusoul Red as the group leader, and sought to become one due to believing his high performance in battle would gain him the position. Unfortunately, these thoughts are what didn't get him chosen as a Ryusoulger, and he soon began going on a quest to find a place in the world. When he encountered Koh, a squire of Master Red who did become Ryusoul Red, Nada attempted to pass on his ideas, but he only realized his foolishness after retrieving Kishiryu Chibigaroo.

Becoming Gaisoulg
After being rejected as Ryusoul Red, Nada began looking for a way to prove everyone wrong, eventually hitting upon the use of Gaisoulg's armor, scouring the cosmos before being led to planet Nemesis. Shortly after Towa and Bamba defeated Rita (who was the user of the Gaisoulg armor in that moment) on planet Nemesis, the Gaisoulg armor was scattered on the remains battlefield, Nada (who mysteriously was also on the planet), took Gaisoulg’s helmet from the flames and left with it. Wearing the armor, he eventually gained Master Green's memories. Although he became an unbeatable warrior thanks to the armor, the sheer violence of it all made him find it less fun than he had hoped.

Return as Gaisoulg
Nada, now under the identity of Gaisoulg, released Kishiryu DimeVolcano for Wizeru’s purposes. However the Kishiryu was obtained by the Ryusoulgers first. The night after the Ryusoulgers defeated the Shen Minosaur, Gaisoulg met with Wizeru and Kureon mocking the first for allowing the Ryusoulgers to obtain DimeVolcano, which made Wizeru angry and had a small fight with him. Angrily Wizeru asks him why he didn’t got rid of the Ryusoulgers by himself which Gaisorg responded that it was pointless as Wizeru wanted "entertainment". Gaisoulg tells Wizeru that he's going to let him know if he finds something interesting before leaving.

Nada as Gaisoulg later approached Prime Minister Mioko Karino (who apparently recognized him) at her hospital room who tells her that he could have killed her if she wanted. Mioko responded that she and him are similar as both wander with nowhere to belong. Mioko tells Gaisoulg that he might be having trouble to let his past glory go and according to her, Gaisoulg could create a Minosaur by this rate. While Mioko leaves, Gaisoulg asks her where she’s going which she answers where she belongs as she finally found her place.

Aiding Towa
Nada as Gaisoulg meets face to face with Towa who was the last Ryusoulger standing as the others were captured by Wizeru with the power of the Grimoire Minosaur. Gaisoulg had a small battle with Towa in which he easily defeated him. Before leaving, Gaisoulg told Towa “to not rely on his strengths and bring them to life instead” which were the same words that Towa and Bamba’s master used to said.

Encountering the Ryusoulgers
Nada shows himself under his true identity first to Canalo (RyusoulGold), he requests him to take him to the other Ryusoulgers, telling them that he wants to join them on their fight against the Druidon. Later while the Ryusoulgers were fighting the Dodomeki Minosaur, Nada as Gaisoulg attacks and defeats them telling Koh that “The Fun is just beginning” before leaving.

Succumbed to the armor and Joining with the Ryusoulgers
Nada eventually reaches to the point where he cannot control Gaisoulg, thus letting the armor taking over his mind.

Gaisoulg made its way to the Ryusoulgers while the latter were fighting Gachireus and Jack-o'-lantern Minosaur, the Druidon Tribe members retreats as Gaisoulg rampages on site. Suddently, Towa uses the DoshinSoul to weaken Nada's body as a mean to force Gaisoulg to switch a new host, and Melt suggests to use the Minosaur's rainbow rain to accelerate the process to exhaust Gaisoulg's hatred. Gaisoulg attempted to take Koh as its new host but was blocked by the Ryusoulgers and its hatred was expelled by the rainbow rain, relieving Nada and Koh.

After defeating the Jack-o'-lantern Minosaur, the Ryusoulgers return to the Tatsui residence. Nada secretly follows in as Gaisoulg, frightening Ui and Naohisa untill he surprises them by using the Gaisoul Ken as a backscratcher. Then Nada took off Gaisoulg's helmet, showing his gratitude to the Ryusoulgers and giving Towa a payback fight upon using DoshinSoul on him.
