“He’s… dangerous” Iduma and Yamir said simultaneously.

“You know each other?” Naomi looked from side to side, confused.

“No, but this feeling stirring within me is…!” Yamir said as he was getting agitated.

“I remember him PERFECTLY!” Iduma said with a huge smile plastered on his face.

“Could it be that… you know about them?” Yamir asked him.

“Haha, do I?” Iduma said.

Yamir did not hold back as he summoned an exceptionally long spiritual snake that brought Iduma to him and then violently squeezed the lad in midair.

“Stop, Yamir!” Naomi shouted.

“Tell me now!!” Yamir exclaimed.

The child wearing his smug smile gave him the finger. The snake then hurled him away while Iduma used his roots to protect his back before hitting the wall.

“Iduma!” the girl went to him right away.

The kid got up off the ground. The last time the boy felt so fired up was when he fought against Xanthus, on the day they met…

“Why do you have to fight?!” Naomi stood between them trying to avoid the inevitable.

“He knows about my memories” Yamir argued.

Naomi wanted to stop them, but her conscience was telling her to let them do as they please.

“The Hero and the Talking Serpent are considered the most powerful Spirit Mode users in History. I wonder which one is the strongest: Adam’s power or Nachash’s power? Let’s find out!” the red-haired lad said.

“Very well… be devoured!” the green-haired young man took that as a challenge and accepted it.

Yamir did not waste time as he summoned a few snakes that nearly hit him, were it not for the barrier of roots that Iduma created at the last minute. The red-eyed child laughed and went over from defense to attack – a thick mass of roots rushed towards Yamir who copied Iduma and protected himself with a shield made of snakes.

As if they were reading the opponent’s mind, Yamir and Iduma each summoned a dozen roots and snakes that clashed at the speed of light. The battle gradually intensified and at this very moment exactly fifty snakes and fifty roots accurately controlled using the Visibility property were clashing against each other as sparks flew in the air.

“Wow. Both are… amazing!” Naomi thought.

However, there was a difference in strength even amongst Full Spirit Mode users that was about to become apparent… Iduma, who was enjoying himself immensely, went up to the ceiling of the floor swiftly on top of roots, riding them like a surfboard.

“You won’t escape!” Yamir followed him also on top of snakes.

“I don’t intend to” Iduma snapped his fingers and a sizable number of roots he had previously planted grew from the ground.

His trap caught the snake off guard and Yamir would have been crushed had he not created a barrier.

“Why does watching them fight… makes me so sad?” Naomi thought as she almost wanted to cry.

The girl found herself reliving a memory that did not belong to her yet happening in a place oddly familiar to Naomi. In a village on a warm sunny day, two smiling teen boys fought whilst being watched by a gleeful audience. The youngest one was the spitting image of Iduma and the oldest looked like a younger Yamir.

Naomi stared at the person next to her. It was a beautiful turquoise-eyed lass that greatly resembled the woman Naomi saw when she met Core. The girl noticed her gaze and smiled at Naomi.

“Who… are you?” Naomi asked.

The teenager returned to reality without hearing an answer. Yamir closed distance as he was getting more and more obsessed with the possibility of recovering his memories. The snake threw a punch and Iduma bled from his nose.

“If you really want to get them back, you’ll have to hit harder!” Iduma backed off and razzed him while wiping his blood off.

Yamir reached Iduma in the blink of an eye and kicked his enemy’s belly.

“S-So fast…!” Iduma thought as he knelt on the ground.

For hundreds of years in the Underworld Yamir battled easy preys and only now, stimulated by high intensity, did he start to remember his forgotten instincts.

“…It is for these moments that I live!” the crimson-haired boy withstood the pain and stood up as roots surrounded Iduma and snakes Yamir “C’mon… LET’S KEEP GOING!” Iduma exclaimed and the cross around his neck swayed.
