***************************************

On one sunny peaceful afternoon, on the palace all our favorite twelfth idol's are on library garden to learn more about Rainbow Kingdom history with Rimuru to help them. They sat on one the biggest gazebo to get more relaxed.

Everyone was so focus in learning at the gazebo until...

Tamaki : [hungry stomach sound] sorry.

Sougo : we not long just have lunch you know.

Rimuru : well why we don't get some snack and tea, and of course some pudding too?

Mitsuki : oh, nice idea.

Nagi : of course we love for it.

Rimuru : alright i need someone or two to help me to bring it. Anyone want to volunteer?

Ryu : i will help.

Tenn : me too.

Rimuru : alright you two, let's go.

Rimuru along Tenn and Ryu go to kitchen to get some treats for others. But while waiting Riku and Momo saw a spark of light come from a book in side the library and decide to take it and read it together at gazebo.

But after they take it and bring back to gazebo, Riku open the book and bright green light came out from it and cover the whole gazebo.

Yamato : wha-what's going on?

Gaku : what's this light?

Yuki : it's so bright.

Momo : what in the world--

On same time, Rimuru, Tenn, and Ryu just get back and saw from the library door that their friends are get into a book.

Ryu : say, you two also see it?

Tenn : yes.

Ryu : all our friends...

Rimuru : just get into a book?

The three of them rushed to the gazebo and put the snacks and tea on the table before picking up the book.

Rimuru : [pick the book] this is an old language, it says "A tale of Desire".

Tenn : "A tale of Desire" huh.

Ryu : don't know why but i have some not really good feeling.

Rimuru : [open the first page and read the inscription] "when one desire is fulfilled, those who trapped are saved.".

Ryu : should we read it?

Tenn : please Rimuru.

Rimuru : okay. [open the next page]

When Rimuru open the page, they saw of Riku with Momo and Yuki on under a tree close with a large lake with Riku was in middle them. The two senior was getting closer and closer to Riku like want to nuzzle him but ...

Tenn : [close the book intensively] What in the world is happening?! I can't bare to see it more! Momo-san and Yuki-san, what are you two doing with Riku?!

Ryu : [try calm down Tenn] Tenn, calm down.

Rimuru : is that an illusion? or a reality from the book?

Tenn : it's an illusion or reality i can't take it anymore. just how we can save him?

Rimuru : maybe we try open it again?

Tenn then open the book again and this time was Riku with Sougo on idolish7 dorm. Riku in the dorm felt a bit thirsty and headed to the kitchen to drink a glass of water and Sougo there prepared tea for him. They both talked about Trigger and watched concerts even until the next day until their eyes were like pandas for dear god they not like feel tired and still keep going ...

Tenn : NO!!!! [close the book intensively] even i also respect him, but this unforgivable!

Ryu : this time was Sougo-kun and Riku-kun story.

Rimuru : hold up "A tale of Desire", it means earlier was Momo and Yuki desire and now was Sougo desire?

Tenn & Ryu : eh?

Rimuru : i just remember there's a mystery book around this library that can craves person desire.

Ryu : really? and you telling us this book is that book you talk about?

Tenn : [the book he hold was floated and glowing for second and try to hold it] hey, how we can bring everyone come back to us? [the book didn't gave any reaction and he shake it depressionly] just tell us now!

Rimuru : Tenn please calm down. [try to calm down Tenn and open the first page] the inscription said "when one desire is fulfilled, those who trapped are saved.". So according with that if one of our friends desire is fulfilled they all will be freed. Though sometimes i'm still doubt about that one.

Ryu : wait a moment, i think i just remember that all of them is adore Riku and that's mean, they have to do all kind of thing with him?!

Tenn : No!!!!! No way ... If that's what will happen i can't see it anymore.

Ryu : i know this is hard but we have to if we want to safe them all.

Tenn : i know but it's just ...

Rimuru : [put his hand on his shoulder] don't worry, we here for you. I know this hard but let's do this together and save them all.

Tenn finally calm down and strong enough to see the book again, but now was Mitsuki and Riku at dress room, looks like both just have done a job. they both talk a lot about their job so far and Mitsuki invite him to have some donuts at a cafe but right Riku want to reach the door Mitsuki suddenly grab his hand and saying something that unexpected and their face is pretty close each other ...

Tenn : [close the book intensively] Izumi Mitsuki you better not doing something bad to him! [turn to a sad voice] even he saying that to him that i can't from long time ago ...

Ryu : keep strong Tenn, let's see the next. [open the book slowly]

This time was Riku with Yamato at a movie shooting. Yamato was walking to Riku that finish his part for the shooting and currently in break before shooting again and bring him a bottle of water for him. But when Riku just drink it Yamato get closer with Riku face and ...

Tenn : [close the book intensively] that one of old man, he really need some lesson after this!

Rimuru : keep strong Tenn, keep reading.

Tenn open the book again and now was Riku with Nagi at Akihabara. Nagi mostly drag Riku to come with him to some store that make both of them happy and when Nagi ask Riku to cosplay he want to decline but feeling not good so he accept and doing cosplay as Cocona for him ...

Tenn : [close the book intensively] for goodness sake he need some lesson too after this!

Ryu : next Tenn, let's see the next one.

Again Tenn open the book and it was Riku with Iori and Tamaki at college. It looks like the three of them have just finished with their class schedule and will go straight home to do their assignments before going to do idol work. But when on a fairly quiet street even though it's still in the sun, Tamaki suddenly embraces Riku from the left and Iori from the right making Riku shy and confused and the two of them look closer to his face and ...

Tenn : [close the book intensively and ready to trow the book] let's bring this evil book away now [with teary eyes]

Ryu : [panic] Tenn please calm down!

Tenn : is this what they thinking?!

Rimuru : probably the magic of the book make their desire burst out of control.

Tenn : are you not satisfied? is that still not enough? [and the book didn't gave any reaction]

Ryu : probably the answer is no.

Tenn : if that's the case ... I will face all desires or whatever they think for me to see!!

Tenn open the book again and this time was Riku with Gaku at a luxury restaurant for diner, but when Gaku want to say something Tenn immediately close the book intensively with sorrow eyes.

Ryu : Tenn?

Tenn : after this all, i no need to read everything to know what will happen.

Rimuru : it's pretty hurt i can see.

Ryu : but the one mostly hurt is Riku-kun, he probably want to spend his time will all of us or with Tenn. [realize something] Oh yeah, out of all desire stories we've seen there isn't one that tells about Riku-kun desire.

Rimuru : [realize it too] oh you're right now you mention it. "when one desire is fulfilled, those who trapped are saved.".

Tenn : [feel have some hope] that means if Riku's desire is fulfilled...

Rimuru : everyone will freed.

Tenn : then we only can put our hope in that conclusion.

Tenn then open the book again but with Riku alone in a concert stage. He smile and wave to fans at venue that calling his name repeatably and saying encore too. Riku then murmur something but Tenn can hear it too. After that Riku then start to singing and dancing with all spotlight on him that make his aura more bright and bright.

Tenn : wait Rimuru it's clearly somethings wrong with the book.

Rimuru : let's close the book for now.

Without further ado Tenn immediately closed the book, but the book moved and hovered above them and suddenly opened and all their friends came out of the book.

After a while one by one they came to their senses and Tenn immediately hugged Riku because he managed to come back from the book and everyone returned to the gazebo to discuss what had just happened.

Yamato : So you're saying we entered a magic book?

Rimuru : yes, and i also surprised with the book is still in this library after long time probably never get touch.

Riku : ah so that was a magic book, that's why all weird things always happening.

Momo : "A Tale of Desire"

Iori : desire.

Mitsuki : "desire" it said right.

Yuki : i have to go now.

Nagi : me too desu.

Yamato : me too

Tamaki : me and sou-chan too.

Sougo : ye-yes, excuse us.

Tenn : [watching the others go leave the gazebo] you all suddenly feel embarrassing after get back to real world.

Gaku : embarrassing? what are you talking about, i only have a nice time at restaurant for dinner.

Tenn : [with angelic face and voice] that's the only thing that you just to know.

Ryu : [sweatdrop by it and back serious to topic with a bit confused] but then again the book looks so hurt for second.

Rimuru : this is what i though, probably the book can't hold Riku's desire like others because the book is out of it's limits.

Ryu : are you telling that Riku-kun desire is stronger than the book. [he ask back and Rimuru just nodded]

Tenn : that's my twin brother for you.

Riku : [just sip and enjoy the tea and thinking his desire even it's like a dream]

~ Omake ~

In the afternoon when the sun was about to set Riku met Gaku under a tree. Riku invites him to climb the tree and watch the sunset. While they both enjoy the sunset Tenn and Ryu are looking for Gaku to do their unit song practice until Tenn sees Riku and Gaku sitting on a tree watching the sunset.

Tenn : [saw those two alone and rub his eyes for second] is this one of that book of desire illusion. No, this is clearly in real world. No! i can't let it happen! I have to interrupt them! [run to the tree and leaving Ryu that sweatdrop by it]

***************************************

Hi everybody, I'm, Zaher finally came back in her busy time...

because i don't want get stuck here so i made this completely not really related with the main story and 2k+ word !?!?

since i think not really fun if the story is full with some magic battle, idol job on earth, and drama, i was get this little idea to make a little crossover with Hamefura S1 Eps8.

yeah i often get into really bad with Hamefura either S1 or S2, so i decide to write this kind of side story.

(i also love eps8 in S1, not because the romance content but the comedy is awesome)

but since we need someone to became the victim of the teams desire and the reading of the desire book i really want to pick Riku for desire victim and Iori for the reading desire victim.

But i thinking back for the reading victim, i think it will be more funny if Tenn that see the others desire to his (cough) beloved (cough) twin. of course with one that help Tenn to calm down along with Rimuru here.

and yeah i really love to see this (with Tenn became a bit OOC but well it's worth it).

oh and with the dots in every desire end was to tell reader-san to imagine your self what will happen in that desire, like in Hamefure S1 eps8 where Mary close the book fast before the UwU part happening...

so see you at real chapter

bye bye 👋👋👋👋👋👋👋👋👋
