I suppose I should be listing copyrights here, but if I said that I didn't own any of the original source and cameo characters that appear in this work of fiction, and that they belong to their respective owners, the Onmyou Bond scenario belongs to Kidzexion, The One Mind, One Heart arc belongs to White Hunter, The A Destined Friendship arc belongs to Zaix-fukutaicho, and others many of which belong to sunrise or whatever company owns Onmyou Taisenki, I suppose that would be enough, right?

5:30 AM. Rikari's room.

Eternal Wind began playing from Rikari's Drive, an flashing icon of Sentsa alternating between sleepy-face and awake-face appearing on the screen.

~Almost like shards of sorrow...~

Rikari slowly picked the Drive up to stop the music, sitting up in his futon to stretch afterwards.

"Ahhhh... I feel great this morning."

Getting out of bed, Rikari noticed what he assumed was his new school uniform folded up on the floor next to the door.

"Riku must have slipped in at some point. I guess I'll have to get used to wearing stuff like this again... And while I'm at it I should probably get some silver hair dye on the way home today."

Rikari fumbled around with the clothing for a little bit before getting it on correctly, then found a pocket to put his drive in during school on the inside of his jacket. Heading downstairs, he found that Riku was already awake, and cooking breakfast.

"Well, you're up awfully early."
"You're one to talk. You passed out on the train ride home last night."
"Ehehe... I blame all the excitement. And the fact that I had an ACTUAL mock battle before the karaoke dinner."
"Mock battle... Oh! you must be talking about that game that Souma pretty much funded all the way through."
"Yep. The best part was that Sentsa was in the game, albeit as extra content. I'm relatively sure I gave the crowd quite a surprise when I used him."

Rikari sat down at the table.

"By the way, what are you making for breakfast?"
"Well, since we didn't have eggs until last night, I couldn't have made you a proper meal, but now, we do, so I figured I'd try my hand at making something using boiled eggs."

The pot containing said work-in-process eggs was beginning to boil over.

"Want some help?"
"Ehehehe... Sure."
"Well, first thing's first. You're cooking them at too high a temperature. If the water boils over then there's almost certianly something wrong..."

Getting up to take a look, Rikari was pleasantly awarded with the fact that the eggs hadn't broken yet.

"And that's one thing you're doing right. Say, I know I lived here for about a year, but I never did find an egg timer lying around. Do you have one? They really help when you're making these."
"No. I don't."
"Well then, I'll have to fix that when I go to buy my hair dye after school. By the way, just out of curiosity, were you going to go do something with Zaen today?"
"Yeah, why?"
"Okay. That means I have the afternoon to myself... I mean as much as I'd like to join you guys, I kind of still need to take care of getting resettled... Maybe I should find Masaomi too if he's still around."
"Understandable... Oh, but I don't know where Masaomi would be. He probably went back to his own time again."
"Really? How were he and Kibachiyo doing?"
"He'd resolved his contract with him, but otherwise fine."
"So wait, do we know where Kibachiyo is now?"
"He's probably in Naraku. You could always go looking around at the shrine for his Drive and find out, though. I'm pretty sure that he left it there when he left for the second time."
"And that's another thing to add to my to-do list..."

Rikari pulled out his Drive, pulling up the holographic GUI, then pulled up his to do list for the day to add another task to it, a small chibi Sentsa with a happy expression appearing when he'd done so.

"I still wonder how you managed to do that."
"Came with the upgrade. I think it's because it ate my phone and went into overdrive."
"I guess that works."
"Anyway, I'll prepare the rest of breakfast now. Don't worry."
"Thanks... Despite things going back to the way they were before for four years, my cooking still never got any better."

And so the morning went on. Eventually the party left for school, meeting up with Zaen on the way.

At school, just before class...

Ruleo was looking at the classroom with a very confused look on his face in his euphemeral form.

"Oh, right. This is your first time in a school, isn't it?"
"So that's what this place is called. Noted. How long are we going to be here for?"
"You'll get used to it eventually. As for how long... well it's better to say it doesn't last very long."
"Heh. Kogenta was pretty impatient when he first had to deal with this."
"You stay out of this Sentsa!"
"Wanna fight about it, Kogenta-chan?"
"-Chan? What the hell?"

Sensing trouble, Rikari quickly intervened in the argument.

"Now you two, calm down. We're in a school, and I don't want to deal with you guys fighting like always on my first real day back."
"I don't wanna."
"Too bad. If you don't, I'll have to punish you again after school, regardless of what Riku thinks of it."

Kogenta immediately went back into Riku's Drive, with Riku, who was talking to Zaen the whole time, giving Rikari a 'What the hell did you do to him' look.

"Oh relax I only..."

Rikari walked up to Riku, whispering in his ear. Riku made a few faces ranging from 'do not want' to 'okay flat what'.

"...And that's how I made him submissive to me."
"I didn't need to know that. More importantly, how did you even manage to do that?"
"That's a secret."

At which point class started.

Later, during team games...

The game of the day was volleyball. Riku, Rikari, and Zaen had formed a team and were currently up against a kid named Sai, along with two other kids from class whose names Rikari hadn't bothered to learn. Rikari pegged Sai right away with a shot to the left shin.

"Whoopsy. Did I do that?"

Rikari was openly mocking him while walking under the net and over to him to help him up, quickly pulling the young man close to him as he helped him up, whispering into his ear.

"Listen and listen good. I know you like causing trouble for Zaen, I have a friend like him in another town. If you know what's good for you, you'll stop messing with him and actually treat him decently. You might even find out that you have a thing or two in common with him. Also I sense something from you, but I can't figure out what it is. You should really start watching your back, or else something might happen, and I guarantee it won't be me."
"Wha-"

Rikari shoved Sai away, going back to the other side of the net.

"So, now then... Shall we play volleyball?"

At which point Rikari served the ball, partially singing the lyrics of YOU GET TO BURNING as the game went on. At the end of it, Zaen ended up being the MVP. Rikari was in shock, seeing as he was probably more fit than him. He was clearly slipping...

The rest of school went on. At some point, Rikari saw Sai and Zaen talking. They looked like they were getting along, well, at least somewhat.

Later, after school, on the walk home...

"So Zaen, how'd you manage to outdo me in volleyball, anyway?"
"Well, I'm kind of embarrassed about how I managed to do this, but... I kind of got bored and trained myself."
"And there goes my ego. I was in the Fukumaden for four years training my ass off, and I get outdone by somebody that was bored."
"Eheh. It's not something I'm really proud of..."

Later, once the party reached Riku's house, which had a whole bunch of boxes in front of it...

"Anyway, I need to go see Yakumo today, so I'll be taking a trip through the Fukumaden. I'll try to be back before sunset. Can you guys handle taking in these gunpla?"

And with that, Rikari went inside, quickly getting changed into his casual clothes, minus his vest before heading out to the shrine.

At the shrine...

"Fukumaden Gate... Invoke!

The Kimon in the Fukumaden began to glow a dull purple before Rikari walked on top of it, vanishing into the depths of the shogi door entrance of the Fukumaden.

"Alright... It's just a matter of selecting the right door now..."

After a little bit, Rikari had managed to locate one of the entrances to the Taihaku Shrine area.

Upon exiting...

"Woah!"
"Oh. Sorry. Did I surprise you?"

Rikari had somehow landed on top of a rather well endowed for her age Miko. She had violet-blue hair and greenish-brown eyes. Upon helping her up, Rikari took a second to look at her.

"Wait a second... I know you... Nazuna?"
"Rikari?"
"Wow, you certianly grew up a lot in the four years, in more ways than one."
"Cut the flattery. You know I have a boyfriend."
"Yes, and he's very lucky to have you. Anyway, do you know where Yakumo is?"
"He's out at the moment. Do you want me to leave a message?"
"I need to get into Naraku. I think there might be someone there that I would very much like to meet with."

At which point Yakumo walked in, a grocery bag in his arms.

"I guess I could help you out, although I question why you didn't just go there yourself."
"Finding that place is harder than you think. In the four years I was there, I never managed to find my way there."
"That's understandable. Let me go get my Drive and I guess I'll show you the way."

And with that Yakumo vanished into another nearby room, coming back five minutes later, dressed in casual clothing.

"Sorry. I had to get changed, too."
"Understandable. Now let's get going."

And so the duo went into the Fukumaden, and then into Naraku from there, ending up in a room with a weird turtle-shikigami, whom Rikari asked for directions to the Shikigami graveyard from there.

Upon reaching the Shikigami graveyard...

"Well, here goes nothing."

Rikari pulled out his Drive and a few Toujinfu, setting down the toujinfu in a pentagon shape, the characters for Seiryuu appearing each time. When he was done, he was standing in the middle of the circle, holding his Drive out in front of him.

"Seiryuu no Kibachiyo, if you are in this place, I order you to show yourself to me!"

Rikari flipped the screen foreward. Green shogi doors appeared in front of him.

"Rikari?"
"I came to get you since Masaomi and you finished your contract."
"You're really late in that case."
"Sorry. Just found out this morning. Anyway, if you need a proper contract, I'd like for you to journey with Sentsa and myself to the end of the rainbow."
"That's awfully broad."
"It's a metaphor."
"Seems legit. I guess I'll bite and join you."
"Very well then. Seiryuu no Kibachiyo, I hereby make a contract with you! Stay with me 'till the end of the rainbow!"

The shogi doors opened up, Kibachiyo stepping out of them shortly before turning ethereal and vanishing into Rikari's Drive, which flashed the colors of Masaomi's Master Drive for a moment before returning to it's normal color, with a blue scale attached to a string materializing on Rikari's Drive afterwards.

"Now then, I don't know any of your In. This is a problem. Is there a place I can go to get them all?"

A somewhat-chibi Kibachiyo face showed up on the screen of the Drive.

"Well, Usubeni had them in a book, and Gasshin used to watch her, so he knew them by memory. I guess if you could somehow find the book or Gasshin, you could learn them all. Otherwise I only have one In that I can theoretically tell you."
"Great. So that means I get to improvise. At least I can utilize the Synchronize function of this Drive if I can ever figure out how to make it work. I think. Anyway I have Riku waiting on me at home, so let's go back already."

And so the newly contracted Shikigami and Toujinshi went back to town. It was still late afternoon when they'd arrived.

"Well, that's a good thing. I still have time for Gunpla and homework."

And so Rikari went back to Riku's house, where he found Kogenta and Ruleo sparring in the front yard, somehow unnoticed by the other people walking by. Ah, it was good to know that Masaomi's seal was still in place after all this time. Walking inside, he found Zaen and Riku working on their math homework. It looked like Zaen had been doing some extensive tutoring, too.

"Wow Riku. Still not good at math?"
"Erm..."
"Don't even bother. I'll help too."

And with that, the rest of the day was spent between a combination of homework, dinner, gunpla, and gaming. The whole week pretty much went like this too. And then the weekend rolled around.

Zaen had invited Rikari and Riku over to his place for breakfast on saturday, followed by an attempt at training. Riku hadn't woken up yet, so Rikari just slipped out the door.

Later, at Zaen's place.

Rikari knocked on the door.

"Hello? Are you in there Zaen?"

A minute or so passed, and he knocked again, Zaen coming to the door this time, with Ruleo poking his head out behind him.

"Where's Riku?"
"Ehehe... He wasn't up yet so I figured I'd let him sleep in. He'll be here eventually, I guess."
"That's just mean."
"I never said I was nice all the time. Anyway, I'm interested in that book you mentioned before. I took a field trip to Shikigami hell on Monday and contracted a Shikigami that I've been meaning to find, but I don't know his In. He said that I'd either have to track down a guy that I'm relatively sure is long gone, or that I'd have to find the book where one of his previous contractors had stored them."
"I'm relatively sure this isn't the book you're after, but there's no harm in checking, I guess..."
"Cool."

Upon entering Zaen's house, Rikari pulled out his Drive.

"Shikigami! Summon!"

Two silhouettes flashed in front of Rikari, Kibachiyo popping out of the Shogi doors that had spawned, laughing.

"Seiryuu no Kibachiyo! Kenzan!"
"Kibachiyo, Zaen and Ruleo. Zaen and Ruleo, Seiryuu no Kibachiyo."
"The pleasure's all mine."
"N-nice to meet you."
"I don't think we've actually formally met before today."
"Anyway, let's cut to the chase."

And so Rikari cracked open the book that Zaen had shown him shortly after he'd arrived. Sadly, he didn't find Kibachiyo's In. And then Riku showed up. Eventually, the group took a field trip to that keystone up in the mountains nearby. Upon arriving, they ran into an enemy Toujinshi who introduced himself as Tenra. His shikigami was named Iniu no Yuki.

"Shikigami! Summon!"
"Shikigami! Summon!"

Kogenta and Ruleo jumped out of their respective shogi gates.

"Byakko no Kogenta! Kenzan!"
"Byakko no Ruleo! Kenan!"

Rikari held up his drive.

"Shikigami! Double Summon!"

INITIATING FUNCTION: SYNCHRONIZE...

A single shogi gate opened up, Sentsa stepping out, wearing what looked to be bits and pieces of his armor fused with Kibachiyo's armor. Setsumaru had been replaced by Kibachiyo's spear, too. He then spoke in what sounded like a mix of Kibachiyo and Sentsa's voices.

"Byakko no Sentsa! Kenzan!"

A battle broke out, two demon-beast-things jumping out of the bushes, attacking Sentsa and Kogenta.

At some point, Zaen must have figured out another one of Ruelo's In, because a flash occurred in their general direction, and then suddenly Ruelo had a sword. At which point the battle became a curbstomp because the enemy shikigami was promptly sliced to bits before turning into his name and vanishing.

Afterwords, Zaen was a little depressed, but after getting back to Riku's house, Rikari had all but forced him into assembling a gunpla with him in hopes that it would at least keep him busy long enough for him to not feel as bad about killing a shikigami. At some point, Rikari had put on some music and was singing along with it, too.

~At the begining, the bell echos to let you know~

~That it's just a matter of change from a terrible yesterday~

~It's all right, since you're here next to me~

~I'm not alone, and that's what'll awaken my courage~

~The sullen world dazzles so~

~It's so bright, I feel like it's becoming a sun~

~I'll share this with you, the joy of my hopes~

~This cross holds the deepness of our bond~

~The future and the present join together with this puzzle~

~Our hearts connnect for our dream~

~I'll become the proof~

And then the song ended.

"That was the AXESS theme, in case you were wondering. I'm kind of a huge fan of the EXE series, if my customized Drive wasn't enough of a hint."
"I never would have guessed. I don't really watch much TV anymore."

And so the evening went on.

TO

BE

CONTINUED

If anybody's curious, Rikari did end up dying his hair. He bought the dye at some point between leaving for the Taihaku Shrine and heading to Naraku.
