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, many of which belong to sunrise or whatever company owns Onmyou Taisenki, I suppose that would be enough, right?

"What? You don't know a single thing about the In?"
"So it seems..." "Don't say it so flippantly! Well, since it's me, it doesn't matter either way. Normally, people should know at least three or four In."
"For the record, I guessed mine."
"I don't think he cares, Rikari." "Oh fine, I'll just stay quiet." "Anyway, I found this memo inside Grandpa's box." 'I'm willing to bet my completed Freedom gunpla it's probably a key for deciphering that book that he found yesterday.' "How's the Tai In, or something." "what's that?" "It looks like Grandpa wrote this memo. But this place isn't so far away, so I thought we'd go and look tomarrow." "Oh! it seems you're showing some more Touhinshi qualities." "Um, yeah. Well, tomarrow I have a break from school, and I'm not in any club activities anyway. I have lots of spare time." "Why you...! You were only planning to kill time? Sit here!" "I am sitting..." "You... In the first place, a Toujinshi is supposed to..." "And I'm out of here for the night. I'll be in my room working on gunpla, kay?"

Upstairs

"Wow Rikari that was cold of you to just leave him there."
"I'm not dealing with that foul-mouthed brat of a god any more than I have to until he warms up to Riku and loses the arrogant attitude, at least temporarily. It irritates me to no end and is probably going to get him killed at some point. Anyway, help me decide on which gunpla to build next. I have about five more of them, and since I actually have a place to display them, I figured I'd start building them to display here." Rikari then proceeded to pull the gunpla boxes he'd bought on the way home just before the festival started and presented them to Sentsa. "Well... This is odd... How about... The one with the Moustache?" "The Turn A? You have good taste. Very well, Turn A 1:144 it is! By the way, did you know that in the story this Gundam is from, it has the ability to flat out ruin all things electronic?" "Oh? Really? That's certianly a dangerous ability." "Mhm. The pilot of it was a guy from the moon, and he was pretty damn beta at that, so viewers only really got to see him use it a few times, and boy, was it cool." "You're going to have to show me this... Story some time. It intrests me for some reason." "You bet!"

And so Rikari spent a good part of his night assembling a Turn A 1:144 gunpla.

Fastforward to the next day at the train station. Riku, Rikari, Rina, and Momo were all present.

"Soooo why are they here?"
"Good question."
"Hey, Riku. If we're going to be looking for In, how come these guys are tagging along?"
"Asou-san just really wants to be by your side." "Ew, that's gross." 'Kogenta confirmed for childish.' "Sentsa, I win the bet. He's made zero progress since you've last met. Pay up." "Very well. I am a Shikigami of my word too after all... I'll stay out of the drive and let you pass me off as a guy 'cosplaying' for today." Sentsa had attempted to get Rikari to give Kogenta another chance last night while Rikari was partially assembling his Gunpla. It ended with a bet. Had Rikari lost, he'd have had to admit he was wrong and apologize to Kogenta like he actually meant it.
"Why is Momo-chan here?"
"I... Um... "
"Okay I understand that you like him and want to play hard to get, but we're going to miss the train so can you guys hurry up please?" "I-I-It's not like that at all!" 'Lies and slander. I can see right through it, you fake tsundere.' "Look, whatever, we're going to miss the train if you guys don't hurry up."

And then everybody got on the train because Rikari was irritated and used it to corral everybody on.

Later, on the train...

"So we're looking for this person named Kogenta's 'In' or something?"
"He's not a person."
"He's a shikigami. Like me." "Wah! Who are you?" "I'm Byakko no Sentsu. I lost a bet with Rikari, so I have to be out of the drive for now."
"Anyway... What's this 'In'" "I don't really know, but I guess it's a certain way to move the Drive." "Drive?" "Yeah, this thing." "So where is the thing that'll let you 'move' this Drive?" "Mmmm... Actually, I don't really know." "Tachibana-kun, is Tora-san out right now?" "No, he's not out right now, but..." "This..." Rina proceeded to outright spawn a red snapper fish filet with what looked like silvervine garnishes "I made this bento for Tora-san. It's a catnip snapper." "Uh... Will you eat it?"
"NO. WHO THE HELL WOULD EAT THAT?" "A normal cat. But we're Byakko. I might as well attempt to try it though, since I'm going to be out of the drive all day, and I might actually end up having to act like a normal person, so I figure I'll attempt to get some practice in now."

What happened next... was, at best... comedic... at worst, slash... Sentsa found out that his taste buds were super sensative and couldn't eat another bite of it past the first one. He insisted that Kogenta try some of it after he'd tried it, however his face immediately turned red and he was suddenly all over Rikari.

Fastforward to the mountian path since the slash fiction isn't in effect yet.

"Rikkun, is it really here?"
"I wonder..."
The party comes across a statue.
"The priest is pointing the way, so it's probably around here somewhere." "Is it really reliable?" asked a really flustered Momo while flailing an arm. "It's even ritten in this memo. 'Continue in the direction where the priest is pointing."

Cue montage of preist statues and Sentsa being glued to Rikari in every single still.

"So, is that thing surrounded by the barrier it? I'm going to be the first one there!"
"Could an In really be hidden in a place like this?"
Rina looked like she'd just seen a ghost.
"I sense something here. It isn't Tora-san." "Asou-san?"
"It's... probably best if we just leave them be, Riku. We should focus on finding the next statue."

Suddenly glowing Drives.

"Erm, do these things normally do this?" "How should I know? We got them at the same time."

Suddenly glowing path down the rocks.

'I'm almost willing to bet that's the In Riku's after. I'm noting the shape for later... That keystone might work for me though.'

Suddenly Riku falls down some steps and lands flat on his ass.

"Erm, are you okay Riku?" "Ow ow ow..."

Skipping ahead to the keystone.

"I was getting tired of waiting. I was getting bored of waiting here for a Heaven-style Toujinshi, but lookie here, I get to exterminate TWO of them. Man, this really paid off. Now, summon your shikigami! Now! Let's go! Shikigami Summon!"

Cue dull mook summoning scene...

"Kanro no Komaki! Kenzan!"

The girls squeal.
"Momo-chan, take Asou-san and hide with her in the bushes somewhere over there where you WON'T get caught in the crossfire."
"Right."
"Right." "Comming out this far for a fight..."
"I'm not happy about it! Sentsa, if you wouldn't mind?" "Shikigami, Summon!"

Cue flashy summoning sequence.

"Byakko no Kogenta, Kenzan!"
"I suppose I should probably just walk forward now..." Said a rather put down and bored sounding Sentsa as he detatched himself from Rikari's arm and stepped foreward next to Kogenta "Sigh... Byakko no Sentsa, Kenzan..."
"Geez. I thought I told you not to call me out in such a dried up place, didn't I?"
"You're so annoying. Quit complaining." "What's this? What's this? Today's opponent is a little pipsqueak?" 'And there goes my patience for him for the day. I'm going to give Riku a short lecture about this later.' "I feel sorry for you, but we have a new In in our hands now." 'Again with the arrogance. I doubt Riku has figured it out yet, though, so I'll keep quiet.' "We'll get rid of you in the blink of an eye. Right?" Riku flinches. He knows if they don't win this fast that he's getting a lecture. He has to figure out that new In, pronto. "Come on, Riku!" "Ah! Okay! [Shin!-Kan!-Da!-Ri!]" "Geez, it's just a little pest. You're wasting your energy playing with them. Are you saving that new In for a later time?" 'Strike two. One more and I'm going to flat out tell Riku and then bitch this brat to Naraku and back. Come to think of it, what is Naraku, and why did I think of that name just now... All I can think of is that it's a synonym for Hell.' "Now, let's go!" Kogenta goes to take a swipe, and fish-girl dodges it. "OH FOR... Riku, I need you to listen and listen closely. The path down here is your hint. Now I'm going to start trying random combinations starting with the rock shape over there. Have fun. By the way, Kogenta's getting slashed up over there, you might want to make a move fast."

Riku starts flailing about using the only In he knows while trying to figure out Rikari's hint.

"Okay Sentsa, here goes nothing! [Ri!-Shin!-Kan!]"
Sentsa goes flying. However it's not a Hissatsu, or even anything useful. Just a speed boost.
"Erm, sorry Sentsa, that's all I can think of."
"I guess this works. Let's hope that they figure out an In for him soon."

cue Kogenta getting his ass kicked everywhere by the fish girl and a reasons why you suck speech delivered from Kogenta to the Earth Toujinshi and her Shikigami.

"Now! Riku! Let's toss everything we have left at them in one shot!"
"Okay!" 'I still haven't figured out where the In is... Wait, the path... Could he have meant... OH I GET IT! THE SHAPE OF THE PATH!' "Kogenta! This is the new In! [Shin!-Ri!-Shin!]" Kogenta proceeds to slap the fish-girl. "I... Hit her? Anyway let's finish this Riku!" 'Arrogance point deducted. Kogenta used his name." "Gotcha! [Shin!-Kan!-Da!-Ri!]" "Hissatsu Kogetsukenbu!"

Cue the Fish-girl getting sliced up and disintegrating.

Cue Kogenta being a brat.

"I take back all the good things I just said. He's still a brat..."

"Are you the Heaven-Style Originator?"
The voice comes from atop the cliff.
"It does seem like you use a strong shikigami, but if the originator is at that level, that that's a disgrace to the Heaven-Style. Or are you another impostor who has assumed the Originator title?"
"Originator? Impostor you say?"
"I dislike people who just babble on and on... Unfortuneately for you, you'll both be dissappearing here!"
"What's this killing intent?"
'Shit. Kogenta's noticed it too. This is really bad.'
"Be cursed by your own weakness! Shikigami, Summon!"

Cue flashy summon.

"Byakko no Rangetsu, Kenzan!"
"It can't be... He's... That shikigami is..."
"Byakko no Rangetsu. 'We should probably run now Rikari. You too, Riku. This guy is danger incarnate.'"
"'I know. But we have to stay and support Riku, Sentsa.'"
"It's been a while, Kogenta. You too, Sentsa. I wouldn't have thought you would have both made a contract with new Toujinshi!" "M-m-my, how long has it been, Rangetsu? At least ten years, I'm sure." "Same goes for you!"
"Do you know him?" "Not only do I know him... Our history goes back hundreds of years... No, thousands of years." "'Yeah, some of it was in my bed, too.'" "'Stop that Sentsa. You're only going to make things worse.'" "It'd be better if I were the only Byakko." "Byakko? A Byakko just like Kogenta and Sentsa?" "Riku! This guy is completely different from the others whom we've met up until now. Put everything you have into this!"
"Rangetsu, sorry to interrupt the moment, but let's settle this for them." "Yeah." "Let's go! Rangetsu!"

Meanwhile, in a location nearby...

"This doesn't look good! Kibachiyo!"

Back to the present location.

"Descend into Hell! [Ri!-Da!-Ri!-Shin!]"
"Hissatsu! Resshi Taigyakuken!" And then a sword was thrown at the sky. It came back much bigger. And on fire.

Suddenly Card barrier.

"Ahahahahahaha! Run! Run!"
"Hey! What are you doing! Let me go!"
"I like how they left us behind. Let's catch up with them shall we?"
"Agreed."

So everybody ran away.
Later...

"Man... I'm beat..."
'Hey... this guy is Masaomi... Right?' "I don't like working up a sweat."
"Thank you so much for saving us from that dangerous situation."
"Erm, he didn't grab me, but that's okay because we still got away. Not that it matters or anything."
"Keh! It was completely unnecessary." "Please excuse him." "No, it's fine. You guys are my nakama, after all." "Nakama? Who are you people?" "Oh! Oh! I know this one! The Shikigami is Seiryuu no Kibachiyo and he is Masaomi!" "Oh? You're that guy from the other day. So you were moving in with him? 'This is not going according to keiaku, but I can't abort just yet.' By the way, which one is your lover?" Momo flinches and blushes. Rikari blushes slightly at the fact that he was just included in that.

TO BE CONTINUED.
