Chapter 1: The Knight Awakens

Mahora Academy. The Mahora Academy is an academy located in northern Tokyo of Japan. The school was funded by a European during the Meiji era of Japan (1868 1912). At present about 30,000 students earn their education at Mahora, ranging from grade school to university. The academy grounds, which is large enough to be considered its own city district, is where many students spend their free time ranging from shopping to eating a variety of foods from around the world.

Interestingly, behind the Mahora Academy where lies a big tree that spanning over 270 meter. This tree is known as the World Tree.

However, not many people know that a warrior was asleep inside the tree.

A warrior known as….

Baron. Kamen Rider Baron..

In an early morning at Mahora, there are two girls busy delivering daily newspapers to the Mahora residents.

One of the girls is in her teenage age around 16 years old with orange hair and ponytail style being held together with bells. She also has a pair of different coloured eyes (AKA Heterochromia) with blue colour on the left while green colour on the right. Currently, she is wearing the Mahora Middle High School student's uniform. This girl's name is Asuna Kagurazaka.

Another girl with her also is in her teenage age as the same as Asuna. She has long black hair and has a pair of brown coloured eyes. She also seem to be a cheerful type and like to be friends with anyone. She is also wearing the student's uniform for Mahora Middle High School ass ame as Asuna. This girl's name is Konoka Konoe.

" Fuh… That's the last one. Thanks for helping me, Konoka. I was afraid I would be late for class this time." Asuna said towards her friend. After all, it was also thanks to her grandfather who happens to be the Dean of the Mahora Academy let her to enrol into this school for free since she is from an orphanage but she is willing to repay her debt by delivering the newspapers as her job.

"Don't worry, Asuna. That's what friends for. After all, today Negi had sudden meeting this morning with my grandpa. Konoka said cheerfully.

" Hmph.. Knowing that brat, probably something involve with mag-!" Asuna then stopped before she could said the word.

"Hmm?" Konoka pondered. "What's it, Asuna? Negi's involve with what?" She asked Asuna.

"Nothing! Nothing! Probably about teaching and other stuff! That's all!" Asuna said loudly as she tried to make Konoka about the word she was about to say.

"Well… If you say so. Sometimes I think both of you're hiding something from me." Konoka pouted.

Asuna could only laugh weakly. Not only because she didn't want to involve her with magic bit by spreading a word about the existence if magic will cause a certain 10 years old boy who worked as a teacher to be turned into an ermine. Ever since she met Negi, her life had been turned upside down and had no choice but to help him to keep his secret tightly.

"Also," This caused Asuna to snap from her thoughts as Konoka said "Hadn't you notice that the World Tree seems a bit brighter than usual in the morning?" Shen then pointed towards the World Tree which is glowing unusually.

" Oh.. you noticed it too, Konoka? I thought that I was just only imagining things. I wonder what's wrong with it?" Asuna pondered.

"Well, let's try ask my grandpa about. He might know something about it." Konoka said while Asuna nodded in agreement. They then head towards to the Mahora Academy.

Suddenly, they somehow heard a sound of a zipper coming off.

"Umm… Asuna. Did you hear something strange?" Konoka asked her friend as she heard the sound.

"Yeah.." Then she quickly turned to her back. "OKAY THEN, YOU PERVERT! COME OUT BEFORE I-!
She shouted since she thought it was a pervert but then she gasp as she saw something that she haven't seen before in her life.

A portal in a form of a zipper appeared before them. Inside it was a misty forest.

Konoka then also turned to her back and was surprised seeing the mysterious portal. "A-Asuna.. W-what is that?" She asked Asuna as her body started to shaking.

"…I don't know, Konoka." Asuna answered unsurely.

Before they could see the portal closely, suddenly three strange creatures came out from the portal. The creature's postures was hunchbacked with bulbous back and thick claws. It bodies was entirely grey colored with green highlights on their torso, upper arms and legs. The others had different colour such as red or blue highlights. Their head was round with face that depicted different expressions for each colour.

"A-Asuna…" Before Konoka could say anything…

"KONOKA! RUN!" Asuna shouted as she grabbed Konoka hand and run as fast as they could. The strange creatures then chase after both of them.

At Mahora Academy Dean's Office

Many teachers are gathered in the Dean's Office because the Dean had called them over to discuss something. For those who don't know, they are all mages acting as the teachers of Mahora Acdemy.

Currently, the Dean (Seriously.. Should it be Dean or Headmaster?! GAH!) of Mahora Academy, Konoe Konoemon is sitting on his chair with his usual calm face but the teachers could tell the topic they about to discuss is serious.

"Well, as you all can see, the World Tree is acting strange again." The Dean said clearly to the teachers.

Negi Springfield. A 10 years old mage that came to become an English Teacher at Mahora Middle High School as part of his training to become a Magister Magi. "Umm… Konoemon-san, what do you mean again?" Negi asked.

"This case had happen 10 years ago, Negi-san." A man in his middle age wearing glasses answered the young boy questions. He is Takamichi T. Takahata , a very known mage because of his achievement in the Magical World. He is also known as Death Glasses Takahata. "But this time, the Tree World is glowing longer than before."

"EH? What does that mean, Takahata-san? Is it an enemy threats?" Negi asked his senior.

"It wasn't much a threat, Negi-kun." The Dean interrupted their conversation then continued." Usually, the Tree World would manifests a large amount of magic every 22 years. But it's too early for the tree to release its' magic."

"10 years ago, when the same event like this had happened once. At that time, we felt a strange presence near the World Tree but after a few moments, the presence itself vanish and we couldn't sense it again." Takahata explain.

"I see.." Negi said after understanding the situation.

Some teachers in the office felt grim and afraid that the presence would bring destruction to their students along the residents of Mahora.

"But that presence… It didn't felt like magic or neither kii. It felt like it was from out of this world." The Dean said as he stroked his long beard.

"That's why we all should—"Suddenly, all of the teachers felt tense as they felt a strange presence.

"This is.." One of the teachers muttered.

"That power… What is it?" Another teacher questioned.

Negi also prepared his staff in case of emergency. "Konoemon-san, is this..?"

The teachers began to panicked as the Dean then raised his hand to reassure them. "Calm down everyone. It isn't the same one as the last one." He said.

When the Dean answered their suspiciousness, they began to calm down.

"However" The Dean then stand up from his chair. "We must apprehend this situation and confirm its' objective by face to face." The Dean ordered the teachers as they immediately went to action.

Takahata then patted Negi's shoulder. "Let's go, Negi-kun."

"Eh?" Negi questioned Takahata objectives.

"Asuna and Konoka is in danger." Takahata announces which causes Negi's eyes wide open in surprise.

Back to Asuna and Konoka, they are still trying to run away from those strange creatures. Despite those creatures being slow especially since they had bigger head, they don't feel fatigue which causes the two Mahora students being at disadvantage.

Suddenly, Konoka began to slow down which causes Asuna to ask her friend because she was worried of her since she doesn't have much stamina.

"Konoka! We have to run!" Asuna encourages her friend.

But unfortunately, she's at her limit.

"I'm sorry, Asuna….. but I…can't go on any…. further" Konoka said between her panting. This causes Asuna turned shocked as she watches the strange creatures slowly heading towards there direction.

Asuna just can't let her friend to die like this! She then looked around her and saw thick bushes that could help Konoka to hide without being spotted by thos creatures.

Asuna grab Konoka's hand which forces her to move towards to the bushes."Konoka, hide here for a while." She told her friend silently. It was a good thing that from this angle the creatures couldn't see where Konoka is hiding. Asuna then looked towards the World Tree which has the highest hills and the nearest from her point.

"I'm gonna distract those things away from you then I want you to tell Negi that I'll meet up at the root of the World Tree." Asuna explained to her friend about her plan but she also knew that Konoka will disagree her plan.

"Asuna! That's suicide!" Konoka strongly disagrees.

"We don't have much choice Konoka." Asuna said firmly. She also feel scared but if it's too protect her friend, then she is willing to do anything drastic.

Asuna gave her friend a warm smile to her. "I..I will be back at class in time so don't worry." Before Konoka could talk back, she then ran off to distract the strange creatures away from Konoka.

"Hey! Right here you goofballs!" The strange creatures then started to chase after Asuna as she went to the other direction to get to the World Tree.

Konoka had kept quiet inside the bushes so that those creatures couldn't find her. She could pray Asuna for her safety and could make it back without any harm.

After the strange creatures left, Konoka hurriedly get out from the bushes and went to search for Negi.

Inside the current glowing World Tree, a body of a young man is laying on an empty space. It was as if he was sleeping while levitate. Surprisingly, he is fully clothed.

The young man looked like he's around a young adult age range.. He has messy brown coloured hair. He is wearing a maroon red buttoned shirt and grey vest along with a long red and black coat. He is also wearing black pants and a pair of boots.

Slowly, the man began to open his eyes revealing a pair of brown coloured eyes.

Where am I?

The man questioned to himself.

But soon, he'll get his answer.

With Negi and Takahata

Negi and Takahata are searching for Asuna and Konoka whereabouts until they heard a cried.

"NEGIIII!"

Negi turned to his back and saw a tired looking Konoka running towards him.

"Konoka! Are you okay?" Negi asked the usual bubbly girl as she tried to catch her breath for a while. Then Negi felt something's wrong. "Where is Asuna? Wasn't she with you this morning?"

"Negi! You have to help Asuna!" Konoka cried.

"Calm down, Konoka." Takahata said. "Now, take a deep breath and then tell us what happen to Asuna."

Konoka nodded and then took a deep breaths before telling both teachers about everything that happened early.

"Me and Asuna was about to finished delivering for the newspaper but suddenly there were strange looking creatures that we haven't seen before came through a zip-like portal and the chase after us. A few moment later, I couldn't keep up so Asuna hid me in bushes while she distract those things to the World Tree." Negi and Takahata was shocked. They need to find Asuna immediately.

"The last thing Asuna said was to tell Negi to go to the World Tree. Negi, you have to.." Before she could utter a word, she then fainted because of exhaustion. Takahata was able to caught her before she collapse to the floor.

"Takahata-san, please bring Konoka to the infirmary. I'm going to save Asuna." Negi said with full of resolution.

Takahata then nodded. "Okay then, Negi-kun. Please save Asuna and be careful. We may don't know who or what are this things." Then he left to the infirmary while carrying Konoka.

Negi hurriedly use his staff and chant a spell to fly by riding it. Then he head towards to the World Tree while hoping he wasn't too late.

With Asuna

Asuna finally able to reach the World Tree safely but unfortunately, she ran out of stamina. She panted heavily as she hanging on to one the World Tree's roots. Watching the World Tree closely, it was indeed glowing beautifully.

However, she wasn't able to enjoy the scenery when the strange creatures finally able to catch up with her.

Asuna then tried to run again but she couldn't move a muscle. She finally reached her limit. The strange creatures began to crawl up slowly. It felt like time is moving slowly. It was trying to make her suffer as her death is coming slowly.

Then, one of the creatures finally reached to her and raised it claw to attack her, she assume.

'No…This can't be happening. Takahata-sensei…. Negi… Anyone…HELP ME!' She thought to herself.

Suddenly, the World Tree began to glow brightly which engulf the area surrounding it..

Negi

The young mage who's currently heading towards to the World Tree as it suddenly glows which causes him to cover his eyes.

'What's happening?' He thought.

The Dean's Office

Konoemon who's watching the current World Tree from his office with a serious face.

'This energy…it's not from him.. But who?' He thought to himself.

He just hope whatever or whoever come out from the World Tree has good intentions with him.

World Tree

Inside the World Tree again, the young man who's still trying to remember before he was in this state. He closed his eyes as he tries to remember everything and then..

The memories began to come back…

Zawame City…..

Team Baron….

Sengoku Drivers…..

Helheim…..

Overlords…

The Golden Fruit…

Finally..

Suddenly, an apparition appeared in front of him as it turned its' shape into a man. The man looked like he is around in his adult young age same as the other man. He has clean blond hair with a pair of red eyes. He also wears a silver armour with a white cape. This man is known as..

"Kazuraba….Kouta" The brunette muttered as he suddenly remember the name of his rival.

The man who is known as Kouta Kazuraba who has gained the power of the Golden Fruit which turned him into the "Man of the Beginning", then smiled towards the brunette and spoke his name.

"Kumon…Kaito."

Kumon Kaito shrugs and then said,"What…Starting to get bored being a Kami?" using an uninterested tone.

Kouta then chuckled a bit towards his old friend/rival attitude. "You still haven't changed at all." He said.

"Hmm…Of course. It'll take more than beating me to change myself." Kaito said. "However" He looked towards Kouta. "What're you doing here? After you had sealed me inside this place?" He asked with a serious tone.

Kouta faced then suddenly turned serious. "The Planet of Helheim was attacked by Inves." Kouta said without hesitation.

This causes Kaito's eyes to widen. "What do you mean!?" He asked back. Did the Inves already lost control? Did Sagara tried to destroy that world? Will there be another Helheim invasion?

"Even I don't understand but based on what Sagara said, there's an another Helheim from different universe trying to take over ours." Kouta said with a sad tone as he thought he finally stopped the Helheim invasion once and for all. But now, there's another Helheim he had to deal with.

"A Helheim from another dimension?" Truth to be told, Kaito wouldn't believe such things like different worlds or dimensions. However, this words come from Kouta who's always serious whenever there's a threat and also Sagara shouldn't be taken lightly since he is the Helheim Forest itself.

"Mai is trying to find the whereabouts about the another Helheim however up until we couldn't find anything because our powers can't reach it. Also, Takatora and Mitchy are also lending their hand to help us to fend off the Inves." Kouta explained to Kaito.

Kaito then scoffs. "Hmph.. So your power as the Man of Beginning are useless in this situation." Kaito with rude tone. "So, why are telling me this? It's not like I could do anything since you sealed me in this tree?" Kaito asked.

Kouta kept silent for a while when Kaito asked those questions. It felt like he was keeping something in his mind however it's time to unveil it.

"Kaito" He then shoved his arm towards him. "Will you lend us your strength?" He asked or more to pleaded to him.

Then, Kaito looked at him strangely for a few moments. He didn't expect for Kouta to ask for his help.

"An organization known as Black Bodhi" Kouta then showed him an image of a snake symbol. "They had already build an artificial Helheim before we used the Sengoku Drivers but Sengoku Ryoma was able to destroy it. However, 10 year has passed and now they had created an another artificial Helheim." Kouta explained.

"Takatora and Mitchy are already got their hands tied with the Inves that are attacking Planet Helheim. That's why…" Kouta paused then he took out a Sengoku Driver and a lockseed with a code LS-08 and a banana on it. "I am asking you not only to fight for yourself or your beliefs, but also for your friends and everyone in this world."

Kaito still stays silent. After his father's construction company was shut down by Yggdrasil Corporation, he firmly believes that those who have more power will destroy the weak and view himself as the weak ones to gain more power. This leads to his cold attitude to everyone else.

Then his memories flashed remembering about his dance team, Team Baron. Zack. Peco. He's willing protect his teammates from the Inves by resigning his position as the leader. Ever since he met Kouta, his way of treating others also started to change, a little.

Guess Kouta's influence is starting to rub off on him.

He then chuckled to himself as Kouta look at him strangely.

Start BGM: Unperfected World by Kobayashi Yutaka

Kaito took the Sengoku Driver along with the Lockseed from Kouta and a smile formed on Kouta's face when Kaito accept it.

"So" Kaito asked "Who's the bastard behind all of this?"

Kouta then walked to his front. "Kugai Kudo. He's the first person to test the Sengoku Driver before Takatora. But, the Sengoku Driver went out of control and then caused him to vanish." Kouta explained. "However, he came back again and became the leader of Black Bodhi" Kouta then took out his right hand as a bright fruit with an apple shape began to materialized on his hand. But at the same time, he fell to his knees.

This caused Kaito surprised and tried to help him stand up but Kouta just shrugged it off and gave Kaito the fruit he just materialized.

"After you eat this fruit, the seal will break….and you will be free again." Kouta said as he panted lightly. "Daijoubu…. I used a bit of my power to create it." He said to reassure the worried Kaito.

Kaito look towards the fruit and then look back towards Kouta which he nodded. Kaito then took a bite of the fruit as suddenly his body began to glow and light particles came out from his body.

"Saa… Kumon Kaito"

Kaito then put the Sengoku Driver on his waist and the belt strapped around him. Then he held out the lockseed he just received from Kouta as he pushed the lock.

BANANA!

A zipper-like portal opened above Kaito and a metallic banana descended from the portal.

"Unleash your power"

"Henshin" Kaito announces as he whirled the lockseed and then put it into the Driver. Afterwards, locking it which causes the Rider Indicator shows a red knight themed faceplate to appear.

LOCK ON!

"To protect the humanity"

Then, he reached for the cutting blade and then pressed it to cut open the lockseed, which revealing an image of a peeled banana and the background showed an image of a spear that modelled based on a banana.

COME ON!

"To avoid another Helheim invasion"

The metal banana then landed on Kaito's head as a red body suit with silver chain mail-like material on the chest and silver gauntlets. While inside the metallic banana, an armored red helmet with knight-like feature is formed. It has yellow trimmed white face guard that has blue rectangular gem on the forehead, red faceplate that separated visor that has white grills as the outer section, while the back of the helmet was a silver attachment with yellow horns resembling a banana peel curved upward.

Then, the metal banana opened and folded out to form an armour over his body. The either side of the banana folded down to attach his shoulders revealing a yellow armor with black colored on the tip while the sides folded onto his chest and back as it created a splash effect which causes the visor to lit up yellow light while the jewel on his fore head flashed. A spear with a peel banana-like feature along with a hand guard appeared on his right hand. With that, the transformation finally completed.

BANANA ARMS! KNIGHT OF SPEAR!

"And…"

Kaito finally becomes Kamen Rider Baron!

Kaito then gave a glance towards Kouta to hear his final words but before he could, his body began to glow as the effect of the fruit he just ate is starting to kick in!

However, he was able to hear it.

"Protect Asuna Kagurazaka."

And then, he vanish leaving dust of particle in his place.

Kouta then looked upwards. "I'm counting on you. Because this world now needs you…"

He then vanish as the same way as Kaito, heading back to Planet Helheim where he had another duty to take care of.

Back to Asuna

Asuna, who shielded her eyes from the bright light then opened her eyes slowly. Right now, she doesn't know what to do against those creatures. She just hoped that Negi had arrived to do something about it. But she was shocked when suddenly, she was surprised by what she saw in front of her.

A man in an armor with red and yellow knight themed appeared in front of her.

However, she couldn't see clearly as she felt so tired since she ran for almost an hour without stopping. Then, she fell on to the ground.

At the same time, Negi finally arrived to the scene. "Asuna!" He shouted when he saw one of his students fainted. But when he saw the armored man, he grab his staff as he readied himself in a battle pose, in case he's also an enemy.

The armored man glanced towards Negi. "Hey, kid… Is she someone you know?" He said as he directed towards the fainted Asuna which causes Negi to flinch a bit as he nodded. The armored than carry Asuna in bridal style as he head towards Negi and lay her body in front of him.

Negi went to check Asuna if she's in critical condition and need to see a doctor. "Is she alright?" Negi asked worriedly.

"Don't worry. She's just tired and need to rest for a while." The armored man said to calm Negi down.

This caused Negi to feel relief as he was glad that Asuna is safe. However, he didn't realize about the presence of the strange creatures who are crawling behind them until he finally notice them.

"W-what are those!?" He shouted as h felt surprised seeing something out of this world.

"Inves" The armored man answered.

"H-huh? In…ves"

The armored man then pulled out his spear which have a peeled banana look as he walk towards to the Inves. "No worry kid. I'll settle this." He said, as if it was an easy job for him.

"U-mm…Ano!" This caused the armored to stop for a while as he waited for Negi to finish his question. "Can I ask your name, Knight-san?" Negi asked nervously.

The armored then face towards Negi as he tell his name. "Kaito. Kumon Kaito but in this armor," He paused as he readied his spear to attack the Inves and announces his alias,

"I AM BARON!"

Baron charges towards to the Inves as he slashes one of them with his spear which causes sparks and then slashes another as he hit the last one by spinning his spear which causes it to fall down. But it didn't causes much damage as all of the Inves rose up and begun attacking Baron with their claws. However, it didn't stopped him to attack them again.

He evaded their attacks and then elbowed one of them and kicked another Inves from his behind. It was obvious that the Inves doesn't fight strategically and had no sense of teamwork. He then pierce one of the Inves and twirled around then slashes it which causes a lot of damage towards it.

Negi, who watch throughout the battle from side line was awed by how strong the man who known as Baron is. He was able deal with these monsters-like creatures single handedly.

Finally, all of the Inves fell down in a group, feeling weak since Baron had caused many damages to their body.

Baron, who was in front of them then push the Cutting Blade on his driver three times as the belt announces,

BANANA SPARKING!

"This is the end." He said calmly as he thrust his spear into the ground which causes the ground to shake a bit. Suddenly, projectiles of giant Banana form came out from the ground where the Inves creature was standing and then destroyed them instantly after taking hits from those projectiles.

BGM End

Negi covered his eyes from the explosions from the destroyed Inves. 'I had never seen this kind of power before! Is this magic too!?' He thought.

As the smoke from the explosion had subside, Baron then unlocked his lockseed.

LOCK OFF

The suit of the armor then vanish as it was replace with the appearance of a young man. It is Kaito Kumon. He then looked at his lockseed for a while and put it into his pocket as he approach towards Negi.

But before he could, he felt a pat behind his back and as he turned to his back, he met a man around his thirties wearing glasses. It was Takamichi T. Takahata!

"Excuse me there, young man. Can you follow me to the Dean's Office?" He asked with a smile on his face.

From that point onward, it was a beginning of Kaito's life to fight the unknown Helheim invasion and search for his new purpose in his second life.

Author's Note

Wow… This could be the longest writing that I ever wrote.

I got this idea two weeks again when I was watching the finale of Gaim and reading some Negima fanfictions at the same time. If you guys didn't notice, this story takes place 10 years after the event of Gaim and before the Kyoto arc featuring Kumon Kaito aka Kamen Rider Baron.

Anyway, what do you guys think about this story so far? Sorry of there are some misspelling or wrong grammar but I'll try to improve in the future. I'm quite happy this month since I got good grades for an important examination and I did study in a college for the past 3 month for English subject so I hope whatever I learn from there will help me in this site. If the action scene kinda lame, then I'm sorry since I'm not used to it. I'll try to improve from time to time.

Please and review and see you guys in the next chapter. If I didn't have any troubles again.

Kaitz out.

PS: Any other ideas for the Title Name? I can't get any ideas except that one but if you guys like it, then I'll leave it as it is.
