Note: Cybersystem Gaiden is set to occur in the world of Cybersystem Chronicles, but centered on another character that is also in the Cybersystem RPG.

Chapter 1: Shieldbearer Born

46 years after Kojuro's passing... or 11 years prior to the start of Cybersystem's story...

Hall of Celestials in Hokuto City, capital of Seikuu...

It is raining on the day I first visited the Hall of Celestials, just like the day when they have finally laid the Solitary Star on his final resting-place here. Beside the pod where his body lies is that of his Navi, the Star Angel. My parents have told me of many stories about the operator and the Navi, especially the last one where the two have fought their final battle and risked their lives just to avert the disaster that could have razed the planet.

Gomen ne... I haven't formally introduced myself... I am Seitamashii Ryuu and I'm four years old this year. My family line has traced its most recent line from that of Seitamashii Hoshi Ken, one of the Solitary Star's closest friends... or acquaintance... as how Granduncle Ken has preferred of saying. My granduncle has joined the Solitary Star under his title, Dragon Omen, while his Navi Dragooner is called the Grand Knight. Coincidentally, his grave has been placed to the left of the Solitary Star's monument, simply to make it clear his role has a great impact on the many missions that the Solitary Star has accomplished.

I will be attending school a week later... in the Academy that is found down a few blocks away. The Academy is also the same academy that the Solitary Star, my granduncle, and many other Seitamashiis have studied in. They say that once someone has completed their initial studies in the Academy, their skills would have been equal to at least two levels higher than the standards. Granduncle has told me stories that they undergone rigorous training in order to pass and gain their place as Netbattlers.

Somehow, I have an equal feeling of excitement and dread as the week draws near to the fateful day that I enter the esteemed hallways of the Academy. Excited because I will get to experience a lot of things such as meeting new people and learning something new... yet dreading as I realize that I will not be returning to my home for a long time... Maybe not even after finishing my stay in the Academy...

One week later...

Academy in Hokuto City, capital of Seikuu...

The sun has been shining brightly at noontime as my parents dropped me off at the room I will be staying in near the Academy. Despite the brightness of the daytime light, the air is surprisingly cool and crisp... Not surprising since Seikuu is located on the Northern Hemisphere. That and it is almost the end of fall. After exchanging farewells, my parents finally left. I hurried to the outlying balcony of my room as I see the car cruising down the road.

School started pretty much the usual way with other schools outside the country. We have Reading, Writing, Arithmetic, and of course, basic introduction to PETs, Navis, and battlechips. While it is interesting to do the various activities that the teachers gave us, it is in the PETs and Navis that I seem to have a lasting interest in.

The next day gave us a lot of insight on what we will be doing for duration of our stay in the Academy. There is actually one wing dedicated for various netbattling needs and skills as well as Navi customizing courses. Another wing of the Academy is dedicated to curricular activities and yet another wing for various extracurricular and sports. We even got to see an exhibition netbattling match between two of the Academy's Netbattlers who have received high ratings from the various instructors of the institute. It is a very breathtaking battle where the two are actually evenly matched despite the differences in the styles that they possess.

For the first two years, all we get to do is the basics of everything. There was nothing difficult in what we are supposed to do as long as we follow as what the instructors tell us to do. After the learning sessions, we get to have fun activities that are supposed to further assist in our learning capabilities. We also get to watch several netbattles and visited many places to learn about many things.

The third year is much different from the first two. We are finally given training PETs with test Navis for us to customize as we please and prefer. The instructors said that the PETs and Navis we have received has special sensors set into them, in order to help them better gauge our abilities in and out of netbattles. Figuring that it is best to focus on the defensive aspect of netbattles while customizing my Navi, I have set it to become tough enough to take even the hardest of blows to it. As well as boosting its HP in order to keep it from getting logged out too quickly in battles.

In the following sets of months, we spent most of our Netbattling classes learning about the various viruses that have existed, as well as their capabilities and weaknesses. We then got to apply this knowledge by fighting such viruses in different simulated battles, either in team or alone. The virus busting sessions are done in various environments specifically suited to the viruses' home environment to add more realism in dealing with them. After those months have passed, I am able to fight with little trouble against many different viruses with little difficulty at all.

I can't wait for the following year to come. They say that it will be the part where we will actually receive our own PETs and Navis for our use. In addition to that, we are to learn the more difficult procedures that are found in netbattling. Everyone else is just as eager as well, unable to contain their excitement as stories and conversations are mostly about the plans that everyone has in customizing their Navis and how they will become the best netbattler around.
