"[Primordial Divine Slime Shapeshifting Arts]: [Primordial Slime Sea]!"
Rimuru combined her two main divinities together into her entire body, her Daos shone radiantly as they fused with her form, she grew hundreds of kilometers long until covering the entire skies, resembling a beautiful sea of rainbow-colored slime!
Kireina couldn't help but feel in awe at her capabilities… Not even she was sure her shapeshifting could extend THIS much without having to spend enormous quantities of energy, which Rimuru did almost effortlessly!
Recalling the past when she first summoned her, when she had just evolved into a cute little, blue-colored butterfly, Rimuru had surely grow so much stronger… It felt like the two were completely different beings altogether.
Yet… she could still tell she was still the same good ol' Rimu, aside from maturing a bit, her personality had changed very little!
And her cuteness was still just as big as her size!
"GUGUGUUUUUUU!"
The enormous sea of flames descended over Rimuru, her sea of slimes easily devouring it all in a mere second, the fires were incapable of overpowering her, having their very particles negated instantly.
And Rimuru quickly absorbed it all, as the Slime Supreme Goddess absorbed a large quantity of energy by doing so! It felt as if this beast was just feeding Kireina's wives with nice powerups.
BOOOMMM!!!
Rimuru then landed on the ground, shaking the whole realm as she looked slightly fatty, but quickly went back to her normal appearance after swallowing all the flames.
"Phew… Burp." Rimuru sighed in relief, rubbing her belly. "That was tasty! I think I got enough Spiritual Energy to do this, look, Masta!"
Rimuru's slime suddenly materialized a heart-shaped, rainbow-colored crystal, a [Spiritual Heart] all of her own!
Ding!
[Rimuru] has completely absorbed the Spiritual Energy on its totality.]
[She has absorbed the [Primordial Rainbow Spirit Fire] in large quantities, assimilating it into her Slime and Soul.]
[A [Divine Spirit Heart: Water & Slime] has been created within her chest.]
[The Spirit Hearts are the cores of all living beings within the Spiritual Plane, allowing them to harbor, control, and unleash the power of Spiritual Energy.]
[Rimuru] Divine Power has developed exponentially!]
She absorbed a lot of flames, yet she hadn't acquired a Fire Attribute Divine Spirit Heart, which made Kireina feel slightly off. Perhaps it didn't matter what element they absorbed; their affinity was already somewhat set on stone?
She started to wonder what sort of Divine Spirit Heart she could create on her own, as she smiled at Rimuru and noticed her powerup.
"Well done!" Kireina laughed. "See, grumpy Undead? With my wives around I've got little to worry about nowadays~"
"You're a bit too carefree, as I said!" Aldrich sighed. "How are you even planning on defeating that thing anyways? Maybe flying into its surface and blast its core would be the better way, but its so big… If you had all your Egos here, you could do what you did to the Ruler's Vessel back then."
"I certainly could cheese it." Kireina nodded. "But this Plane's rather hard to adapt to, some of my abilities are slightly weakened, now that I've realized, as if this world's trying its hardest to suppress my existence. And because I've divided my Egos and Summons with my other Doppelgangers to give them good support, I am left with little options than to rely on everything we've got together."
"I could perhaps do something. If we combine all the Undead we have…" Aldrich wondered. "No, even then it wouldn't be enough, we need more materials! Can you bring things from your Divine Realm?"
"I think we've got a better option at hand." Suddenly, Skadi emerged out of Rimuru's Divine Realm, at her side, there was a beautiful spiritual maiden made of blue crystals.
"We meet at long last, Kireina." Skadi smiled, the beautiful Ice Titaness glanced at the small Kireina, she was really little compared to her huge size. "Thank you for sending your friends to help us survive this far, and well, for saving our lives too… If my husband allowed it, I wouldn't mind paying you with what you like the most."
"What I like the most?!" Kireina asked in shock. "W-What have my allies been telling you about me?!"
"I heard from them that you like big ladies." Skadi laughed heartily. "I can tell, look at that woman! She's huge!" She pointed at Brontes.
"Skadi, huh? The Titaness of Winter." Brontes said, with a smile. "I wonder if you could be worthy enough to be one of Kireina's titan wives?"
"T-That's enough! I don't want any wives anymore; I've grown up as a woman and… I am now a new self! I am focused and-"
"Is that so~?" Skadi whispered to Kireina's ears.
"Uwaaah! S-Stop it!" Kireina blushed trying to contain her lust, but Skadi's teasing were a bit hard to resist.
She was serious in what she had said, Frank was just a one-time thing for her, and she had decided on just pamper and snuggle with her already enormous harem, adding more girls to the list would only make it so she would give even less time to everyone else… Something she didn't like.
"Hahaha! Well, enough with that." Skadi smiled. "I've healed well enough thanks to your cute wife, Rimuru. Oh, and this is my friend, Azurite. She says she's a sister of the ruler or something like that? Anyways, we can talk once we've dealt with this big guy."
"Hi~" Azurite waved her hand, behind her huge Titan friend.
"Oh hi. And yes, please, let's focus." Kireina sighed, even now she was slightly weak to the flirting of beautiful women and handsome men… "Anyways, that thing's not going to go down easily… I could probably deal with it eventually, but if we take too long, your whole Realm will fall apart."
"I know." Skadi sighed, crossing her arms. "But what if… we use this Realm too?"
"Oh?" Kireina quickly recalled the time when the Necrotic Plane Ruler utilized Helheim as his vessel! "You mean… To use this whole Realm as our vessel to fight that giant?"
"Yeah." Skadi nodded. "Are you up for that?"
"Hoh~" Kireina suddenly felt inspired. "I guess that MAY work…"
And at that time, several more figures came rushing from the skies, Nesiphae, Zehe, Truhan, Celica, Uru, Blaze, and Lazuli!
"Mom…! Is it really you?!"
"L-Lazuli?!"
Mother and daughter were finally meeting one another, after so long.
