Unlike his future contemporaries in the modern Ryusoulgers, Towa was once woken from his hibernation far earlier in an age of medieval wonders. Then, with no purpose other than what the now-deceased Master Green had asked of him in the Masters' efforts to stop the Druidon, to find his own way in other lands dealing with the Druidon. This was the purpose he would dedicate himself to with a bequeathed Ryusoul and Ryusoul Ken in hand.

Adhering to this wish to the bitter end, he after a long time would end up in one such land to make something of himself as the Druidon came to him. He become a hero to the people of this land, defending them from the Druidon and other such monsters. Eventually he became knighted, becoming 'Sir' Towa and venerated further with contemporaries like him.

It was not to last however, as in this endless war of protection and acclimation he would find his one true enemy; the Dark Knight Gaisoulg, who like an eternal specter would come to haunt him as they fought again and again until either knight would give out. But it seemed fated Towa would lose in their final confrontation.

He himself could only remember the fight in question, a valiant last stand on this 'Hill of Swords' as he desperately tries non-stop to strike down the Dark Knight, and as he loses consciousness from the combined strain and exhaustion of the fight, could feel like he was finally winning against Gaisoulg for once.

While death didn't come for him and only hibernation could, his sacrifice wasn't in vain and the Druidon in time, were driven back to his homeland. As he is brought back to his home, he is left to slumber forevermore until the time came again, to defend his people from those Druidon once again, and if he should return to haunt him once more, to finally defeat Gaisoulg for good on the Hill of Swords.

Towa had received an invitation for the Super Sentai Strongest Battle, a tournament whose winners were supposedly promised their wish. Entering a Ryusoul Temple, Towa asked his older sister Bamba if she had any wishes, to which Bamba replied that she could not think of anything. Coming across a wall with the Ryusoul insignia, Bamba realized that they had arrived at their destination and so used a TsuyoSoul to break down the wall.

Proceeding through the temple, the siblings found a pile of RyuSouls including a NobiSoul and FueSoul, which they already possessed, as well as a HayaSoul which was claimed by Towa. Also present was an amber RyuSoul which did not react when Bamba attempted to use it via the Ryusoul Ken, with Towa suggesting it was a blank. The siblings than set to find what they had came for, the Kishiryu. However, while searching, the siblings' invitation transported them to the planet Nemesis.

Though arriving after the tournament was won by the Oddball Team, the Ryusoulger siblings arrived in time to save them from Rita in the Gaisoulg armor. Engaging Rita, the duo proved more than a match for her, leading her to take Kagura Izumi as a hostage. However, the Ryusoulgers quickly outmaneuvered her, with Ryusoul Black using the NobiSoul to retrieve Kagura, allowing Ryusoul Green to defeat Rita using the HayaSoul. Leaving Rita to the Oddball Team, the brothers took their leave with Towa saying goodbye.
