Deep out in the desert, a young woman dressed in a light brown cloak armed with a pulsar gun continues to walk alone while surviving the hot weather and going north.
During her time, she reflects her moments with a young man that she has seemingly fallen for. His name was Casshan. But when he was still human, he was originally known as Tetsuya Azuma. Long before he was invaded and almost left to perish, by the notorious Black King and his robotic army. In order for him to avoid death unlike his parents, he converged his own human-self into a Neo-Roid. In-spite that he had reached the limit of his powers, he was able to defeat the Black King and clear out his deceased father's name. After that, he vanished and was never seen or heard from again.
She then resumed her destination until she spots an unconscious civilian from a few feet away from her. By the time she got closer, she made a small gasp. A lonely man was near starvation and thirst as he collapsed on the ground after suffering in this land for several days. She tries waking him up, by shaking his body.
"Hey! Are you alright? Talk to me!"
It didn't take long for him to respond, as he makes a small groan and slowly opened his eyes. Although his body was weak from hunger and thirst, he can still see her gazing at him with deep concern.
"Huh? What are you...doing out...here?" he said, weakly.
"I was going to ask you the same question."
"I was...trying to...find shelter and then...my body gave out." He later began to cough.
"Please, save your strength." she pleaded to him.
That is, until he clasped her hand with his and continued. "No. This is...all that I have...left. But before I go, remember...two things. One, there's a...storm heading your way...and during that...a twister will appear...and it may send you...to...another world. And two..." He was interjected, when he felt his body not lasting any longer. She begged him again to stop, but he pressed forward.
"B-Be...v-very-y...c-c-are-full..." With his last dying breath, his eyes were rolled back and his head turned away while his grip on the girl's hand became limp and fell.
She became very remorseful of his unfortunate passing and placed his hands on his chest.
Later on, as flashbacks of a man that she has feelings for were flowing inside her mind, she became unaware of the sky becoming dark and black clouds began to form very rapidly. Bolts of lightning flashed with vigor as loud thunder ripped through the skies like wildfire, whilst strong and fierce winds have made this storm very unsafe. Yet, for no particular reason, not a single raindrop has fallen.
She later recalled the message from the civilian that she spoke with before his sudden passing.
"There's a storm heading your way and during that, a twister will appear and it may send you to another world."
As luck would have it, the huge gray and black clouds started to form in a swirling rotation. Than in a matter of seconds, it became a gigantic twister with dark blue and gray swirls as the young woman becomes trapped in its wake.
She already began to run. But much to her dismay, the tornado itself was much faster than she is and it pulled her inside. As she screamed in misery and agony, she yells out her lover's name before she disappeared. "Tetsuya!"
Although that it subsided and with the young girl vanished, the storm continued. During its massive outpour, there stood the Imperial Palace that once held the leader of the neo-roids. It was a light blue-green robot with spikes on its shoulders and hips, while it sat on its throne completely immobile with a huge hole on its chest after he was defeated by Casshan. As it sits there alone in the dark empty castle, numerous bolts of lightning appeared and it surged right inside his body. Just like from before, when he was first programmed and became berserk. In the midst of things, the hole on his chest began to close and it was restored where the AI chip inside his body begins to function once again and his arms suddenly starts to regenerate. After a short while, he muttered and breathed heavily.
"I...live...again." His eyes were opened and as he slowly stood himself up, he starts feeling his body. Suddenly, he gasped to see a startling discovery. His arms and hands have been revived and by feeling his newfound strength, he laughed. "Yes! His power is inside of me! How wonderful! I'm stronger than ever!" Then, he remembered something. "But, wait. He's not here. So, how will I track him down?"
When he began to ponder his thoughts, a flash of lightning bursts through the sky once again and as he gazes outside of his deceased hideout, he witnesses another twister forming. But, his body begins to operate and as it does, he now has the ability to read its calculations. "Hmm? I sense something from that twister." He reads the exact co-ordinates from the tornado within his mind. After that, he smiled and then, he leaped high into the air and landed firmly from ten stories high. Then, he heads over to the oncoming twister and hopefully to catch-up with his deadly adversary. But as he got inside, he wasn't prepared of the full velocity of the spinning force in the twister and yelled in pain. However, it didn't last long as a bright light shined on him and like the other victim, he too had disappeared.
