Epic of Caterpillar

"How do you feel, Yggdra? I mean Yggdrantia?" I asked to her, as she started glowing.

"I'm feeling alright! In fact, much better than ever before!" Yggdrantia said happily. "It really feels like we needed to become one from the beginning… And we helped make mama a bit stronger too!"

"Heheh, well, you're indeed a good girl." I sighed. "Now, just rest for the moment, you've already exerted a lot of energy."

"But I want to play and explore!"

FLUOOOOSH!

Suddenly, a large quantity of Spiritual Energy, Life and Nature Attribute Divine Energy, and Cosmic Energy condensed in front of the huge tree, taking the shape of Yggdra, but now holding a beautiful dress that seemed to have been made of a small nebula with many bright stars, her hair also shone like the depths of the cosmos.

"Here! I can do this now!" She giggled. "Ah, well, I could already do it but Druantia couldn't do the same exact thing… But now we can do this while leaving the main body behind, so we can always help mama wherever she is!"

"I guess there's no helping it!" I sighed. "Oh… Actually, I have another idea." I glanced back at Flora.

"Huh?" Flora wondered. "What do you have in mind, Kireina?"

"How about you make a Spirit Contract with her? She's the most compatible for your powers, and you'll get a nice buff that you desperately need." I said.

"Wait, what? Would you let me do such a thing? But… I have only wronged you this entire time. Why would you go so far for me?" Flora wondered. "Ah, are you in love with me? Sorry but after so many years, I have grown to be asexual and aromantic, I can't feel any attraction nor I'm into sexual things and-"

"Geez, stop being such a hard-headed woman for five seconds." I facepalmed. "I'm only doing this because you're a valuable and strong ally! Also, Yggdrantia will get to grow stronger if you allow her to fuse with your Yggdrasil Trees!"

"Which in result will also allow you to gain even more strength, I assume." She laughed. "I guess it is a good deal, fine." She nodded. "Yggdrantia, is this okay by you? I won't really force you if you don't want to."

"A-Ah, me neither, it was just a suggestion." I said.

"Hmmm…" Yggdrantia flew around Flora, glancing at her while squiting her eyes, and then, she flew back into Faylen and then at me. "Oway! They're good people at the end! Faylen too, can't she?"

"M-Me?!" Faylen was surprised.

"Yes! You have a high affinity unlike with Elfina! Ariant and Eriant can draw my power without needing a contract so that's unnecessary, but you seem alright too!" Yggdrantia smiled gently.

"Oh dear, well, if you insist!" Faylen giggled. "I would gladly!"

"Then it is decided!" I nodded. "[Spirit Contract Creation Runes]!"

FLAAAAASH!

I summoned many Divine and Cosmic Runes utilizing my Rune Creation Skill, and assembled them into a powerful Spirit Contract, sharing the powers between Flora and Faylen towards Yggdrantia and vice versa.

Ding!

[A [Divine Cosmic Spirit Contract] between [Flora], [Faylen], and [Yggdrantia] has been created!]

[While [Flora] and [Faylen] can now draw, summon, and manifest [Yggdrantia] Spirit Powers, [Yggdrantia] can absorb their Divine Energies and fuse with compatible areas of their Divine Realms to grow much stronger.]

Threads connected their souls with Yggdrantia, and after just a few seconds, it was completely done. And at the same time, Yggdrantia's powers flew inside of Faylen and Flora's Divine Realms.

She quickly started to slowly merge herself with the Yggdrasil Trees in there. Faylen had a large spirit forest in her divine realm, so it was quite serviceable. Flora was the big one, who had enormous Yggdrasil Trees everywhere.

"S-So much new power!" Yggdrantia celebrated.

"I could say the same!" Flora smiled, sensing Cosmic and Nature Divine Energy flowing into her hands. "With this, I can finally begin to grasp a small part of Cosmic Energy as well. Thanks, Kireina, I will make sure to use this power to repay the debt I owe you and protect you and your family."

"You better do!" I said. "How do you feel, dear?"

"I feel overflowing with energy as well…" Faylen was surprised. "I think I could do anything!"

"Hahaha, for now, you three should train this power with Yggdrantia." I said. "Later I should give Cosmic Energy to everyone anyways… I know you want some too." I glanced at Rimuru.

"Oh really? Then that's awesome too, guuu!" Said Rimuru, happily hugging me with her slimy body.

"Hahaha, alright, alright~" I giggled. "Anyways, I think we should go to the most important place here by now… Divine Realm, open a path to the Realm Core."

RUMBLE!

The Divine Realm obeyed my will, suddenly opening a huge staircase leading underground. Where the Realm Core was floating above a large infernal world of lava and flames, the Lower Realm of Vida which has already been assimilated by my Divine Realm long ago.

"Wow, this place looks like hell!" Laughed Eriant.

"Is this some sort of underground world, beneath your world?!" Asked Ariant.

"Something like that, dears, come down." I giggled, as we walked downstairs and reached the Realm Core. "Frank, can you come too?" I spoke to him telepathically, as he agreed and was instantly teleported to our side.

FLAAASH!

"I'm here." Frank said. "Oh, this place…" He glanced around everywhere. "It's huge!"

"Oh, Frank, you were called here too!" Elfina said.

"For what reason, I wonder?" Fiere asked.

"It is because of his System." I said. "I want his powers to combine with mine, so I'll need him around. Also, I doubt he minds, right?"

"Of course not, as long as I can help in any way!" He said with a gentle smile. He was a really good young man.

"Sniff, sniff.." Rimuru started to smell something on Frank.

"Uwaah?! W-What is it, Lady Rimuru?" He asked.

"Hmmm… You smell like Masta." Rimuru squinted her eyes. "Oh! Guguguu?! Did Masta and you…?!"

"I already explained it to most, but yeah, kind of…" I laughed. "It was just a small affair. Nothing serious."

"I-I apologize if I needed your permission…" Frank apologized, bowing his head.

"Ah… Well, it doesn't really matter! Heheh." Rimuru giggled. "It just means you'll be considered family too, guu!"

"Well, I guess that's right." I laughed. "Though he has a place to go back once all of this is over. I doubt he'll be able to stay as much as he wants."

"Hahaha, indeed, I've got my own big family and all… But I would love for all of us to eventually meet in a big family dinner or something! I'm looking forward to that once our battles are finally over." Frank smiled with hope on his eyes. Even Rimuru found him quite cute.

"Is that so~? I can tell why Masta kind of liked you, you're a bit cute, guu." Rimuru nodded, quickly sitting over my head again. "But I only like Masta guu! So don't try anything funny with me!"

"E-Eh? I would never…" Frank felt a bit offended.

"Rimuru, don't mess around like that." I laughed.

"Hehehe, his reaction was funny." Rimuru giggled. "Don't worry, I'm just messing around, guu!"

"O-Oh, hahaha." Frank was caught off guard. "Anyways, now that- Eh?! What is that huge crystal over there?"

"Oh? That? That's the Realm Core guu!" Rimuru said.

[I'm glad that you're back, Kireina-sama!]

"My beloved!"

And the voices of Andromeda and Astraea echoed.
