Tempest(Book 2): While You Were Away

Chapter Three: Guest Appearance

SunKoko Research and Technology was primarily involved in the field of medical experiments, searching for cures to various diseases and such, though its title suggested a variety of other subjects. Five particular scientists of the company were in Nalan's pocket. Although not a scientist himself, Nalan helped fund the company tremendously, hence being allowed to have his own office in their company building. Unknown to most, however, was his hidden laboratory for experiments he desired to remain secret, in the 30th and top floor of the skyscraper.

It was this lab room to which he took his newly acquired sensu beans. "Is the Permanent Energy Enhancer ready for testing?" The chief scientist, a tall white-haired man, nodded. Nalan took out five of the yellow sensu beans from the bag Soma had given him, and put them into a small round contraption. "You may begin the testing when ready." He walked up behind the scientists, and waited patiently. The head scientist pressed a few buttons, and then pulled the main switch. Two antennas sticking out of the round chamber began to charge with blue electricity. Suddenly, a bright yellow flash illuminated the viewing window from within. An instant later, Nalan looked in astonishment as the beans now had a bright orange glow.

"Amazing! It was a total success! I have successfully created five Super Sensu Beans! Now, to put the rest in. Soon I'll have an entire army of unstoppable warriors! Put the rest in now!"

The head scientist looked at the panel, and shook his head. "Sir, um... I don't think that will be possible. You see, the Enhancer short-circuited, and can't be fixed. It took us years to create this machine. It would be futile to start over now, so..."

Nalan looked at the scientists. "You're right. Doesn't matter anyway. Five is plenty. However, your failure will not be excused. Your incompetence in creating a flawed machine is intolerable." He pointed his right index finger towards the five scientists. Five blue lasers streaked out of it, one laser hitting each scientist. "Hope you will be more helpful in the next dimension." He took the five new beans and the bag of old ones, and left the lab. He then summoned Soma.

"You wished to see me, sir?"

"A present for you, Soma. It is a Super Sensu Bean, one that has been specially enhanced. Try it." He knew she would make a good test subject, especially if there were side effects.

She took it and ate it instantly. "What is so special about it?"

"It isn't digested as normal sensu beans are. It assimilates with the body's immune system, making it extremely destroy you. You're not immortal, but as close as a normal person can get." At that moment, the Super Sensu Bean triggered a quick growth spurt in Soma, increasing her muscles and frame. "It also puts you at your peak energy continuously. Its only drawback, however, is that it doesn't increase your maximum energy after a battle, like a normal sensu bean would. The only way you can increase your top power is by excessive training." He then proceeded to take another special one out, and used it for himself. He laughed hideously as he himself gained its power.

She smiled. She thought, 'Let's try this power out. Heh heh heh."

Tempest had taken to the streets of Southtown to begin his search, but nothing had seemed to indicate any problems. He left town on foot, and walked past the SunKoko Skyscraper. All of a sudden, the top of the building exploded in a large sonic boom, immediately alerting him of trouble. He looked up at the large red blast of energy coming off the building's remaining top, and flew up there immediately.

The ninja Soma looked up at her fine attack as it left, but was shocked when Tempest flew in the way of her view, and landed near her and Nalan. "Well, Korin said it was a dark suited person who attacked him. That must be you. Where are the sensu beans you stole? I, Tempest, will fight if necessary to get them back!"

"They are with me," Nalan said, and pulled out the bag of normal beans. "They will be of little use to you, though. We only used a few of them, in the name of science as well as world domination. This is Soma, and I am Nalan. I am sure you have heard of me at least." He waited for an answer. Tempest just shrugged. "You must not get out a lot. But anyway, we have enhanced a few of the beans with permanent ability, making them what I call Super Sensu Beans. We have used them on ourselves, and might I say they work like a charm." He then showed the remaining three orange beans to Tempest, who looked amazed, yet curious. "Fighting is useless! We are unstoppable now." He tossed the bag of normal sensu beans to Tempest, who tied them around his belt. "If you do want to try and stop me, though, you'll have to beat her." He nodded to Soma, who took a fighting stance, and then proceeded to leave them to battle unwatched.
