When Masao became one of Kurai's Dark lords like Ryuken he was standing in front of Ryuken in his throne room.
"Why did you become a Dark Lord, Masao?" asked Ryuken.
"The Dark King made me an offer something I couldn't refuse, Master," said Masao.
"I see I thought things would be different but now since you learned the truth," said Ryuken.
"I'm sorry, Master but this still will be a stepping stone for me in getting my revenge for my mother," said Masao.
"Alright it seems you have your own plan going now and you are bidding time it seems," said Ryuken.
"Yes, Master I haven't forgotten what you teach me," said Masao.
"Good, Masao even if it wasn't official, I have trained you in the arts of being a Wizard remember in combat intelligence and bravery is the key if it is a battle you can't win then flee," said Ryuken.
"Yes, Master Yamamoto I will remember these lessons for the rest of my life," said Masao. This was the last true talk Masao had with Ryuken before his death.
"Awaken, Tenryujin," said Ryuma. Ryuma Weapon enters it awaken form.
"Awaken, Shi Ryujin," said Masao. Masao's weapon enters it awaken for. Both their energy emits out as they get ready to clash with each other as they slash. Ryuma then slashes an energy blast at Masao. Masao would dodge this and fires his own at Ryuma blasting him to the wall.
"Damn," said Ryuma getting up from it.
"Why am I fighting My master's son…no, I can't have these feelings now he is the one who took my master away from me…But he is the one who saved him," thinks Masao who is starting to get conflicted. Ryuma sees this and fires another energy blast at Masao who then uses a barrier spell before it hit him.
"Stop spacing out it's what going to get you killed," said Ryuma. Masao then gets up and starts to charge his lance up with dark energy.
"DIE!" yelled Masao as he released a charge attack at him. Ryuma almost gets hit but gets grazed by the attack. Masao crashes into the wall going through it.
"Damn it. He getting risky here and might even try to hurt himself just to beat me here. I need to end this," thinks Ryuma. Masao gets out of the rubble. Ryuma stands there waiting for him he even closes his eyes.
"Here I come, Tendo," said Masao lunging at him. Masao goes for a slash but Ryuma parries him and goes in an upward slash on Masao cutting him in the torso. Masao grabs his chest with his left hand on the cut. as the whole world fades away.
They both stand in the woods as it starts to pour down as they both revert their weapons revert to their normal forms. Masao was down to one knee holding his chest with his right hand still. Ryuma then goes and picks up Jigoku No Ryujin off the ground.
"Did you win?" asked Yuna.
"Finish me, Tendo," said Masao.
"No," said Ryuma who was about to walk away.
"WHY KILL ME…" yelled Masao before Ryuma turn back.
"I SAID NO DAMN IT!" yelled Ryuma. "I am done killing people especially those who are victims of the Dark King as well." Ryuma then walks away with Yuna leaving Masao to open a portal to the Dark Realm and struggles to enter it.
