The power of the Slime Family was mighty, the group quickly slashed through their enemies, the Undead Demon Gods who were supposed to be as strong as Pseudo Supreme Gods were of no problem to them! But why were they so powerful? Aside from the incredible quantity of buffs they were loaded with thanks to Rimuru's Path Jewels that enhanced Slime-type allies amazingly higher compared to others, and even allowed her to summon them to battle quickly, there was something else to it! Kireina herself had witnessed when it happened, and it was something that everybody also went through, becoming a Pseudo Supreme Deity themselves.
The Slime Family was big, although they were fairly weak separately even as Pseudo Supreme Goddesses, when they all merged together into the rainbow giantess covered in glorious armor that they were most known as, they received an incredible boost to their combined power. As one, they had the power of many Pseudo Supreme Goddesses fused together, but even more, this power was multiplied several times thanks to their innate powers as Slimes that have been fusing over a long period of time.
Their very evolutions shaped this power into their greatest specialty, and as they created their first Path Jewels, these amazing jewels shaped themselves as their power as well, as they evolved and grew stronger, the girls gained an amazing powerup in fusing, and the path jewels only helped in that regard.
When they all fused after already having ascended as Pseudo Supreme Goddesses, the power of the resulting fusion was astonishing, even Kireina was surprised, even more as the slime family acquired incredible power through the various passive effects of their path jewels and Rimuru's path jewels! For a few seconds, when they went all out, Kireina would be able to feel as if they had become a Supreme Goddess, although this "feeling" only lasted for a single second, the amazing power of their fusion clearly surpassed even Kireina's ability to fuse, as the Slime Family had been specializing into this practice since they were very weak and needed more power.
They were so many and could work together, but always found that working even more together would be always more beneficial, and that was attained by fusing into a single organism, the powerful giantess they fused into, that intimidated everybody in the battlefield with her various powerful weapons. Even when such weapons broke, they were able to just create new ones and continue fighting almost relentlessly and endless.
Their might was admirable, and Kireina couldn't help but smile as she saw the girls fighting, she recalled how they came to be from the very beginning, she remembered that they were summoned similarly to Rimuru. In those times when Kireina was evolving, she acquired the ability to summon "Lesser Water Being" such a Skill had only one-time-use, and it was where Rimuru came from.
However, as she evolved, she acquired newer Skills that helped her summon stronger of these beings, without limits, as long as she had mana and time, she could summon these a lot! Of course, they were very weak, but they were good EXP bags, so she used to summon them in masse and make her allies kill them alongside her so they could constantly abuse such a power and endlessly gain EXP.
Through such practice, many of her allies gained a lot of EXP, Leveled up, and even Evolved, greatly enhancing their strength and reinforcing their skills by gaining skill levels, constantly repeating skills granted skill proficiency back then after all! Of course, what Kireina never expected back then was that she was going to end up summoning some very special slimes, these were the slime family, they emerged one after the other slowly, but from the first one that she decided that they would form a slime team of their own, where Rimuru is still the leader.
These slimes showed up slowly and rather naturally with each summoning session, they were the rare slimes that were stronger than the rest, and also possessed greater intelligence and capabilities, they were always special, in both race and skills, so they were quite incredible when they came out.
After Rimuru, there were several Slimes that Kireina ended calling after her favorite characters from an anime back on Earth, and they were:
An adorable, pink-colored Demon Slime named Milim, the second summoned servant that Kireina ever considered to keep, she had amazing potential and her Illusion Magic granted her great capabilities. Since she was summoned that she had always been pink colored with horns and demon tail, with a charming cheerful and cocky in nature. She has been the leader after Rimuru, and although she's a bit clumsy at times, she was quite powerful.
There was then the blue slime, Ranga, the third slime that Kireina kept. Since she was summoned that she had always been strong and a little of a muscle head. She had the appearance of a beast sometimes, with wolf ears and tail, and even developing claws, making her very wolf-like.
Then came Benimaru and Shion, considered as "twin brothers" by Kireina because both were summoned at the same time, Benimaru since being summoned was brave and energetic, while Shion is timid but lovable. Shion seemed to be a healing magic and status ailments focused variant named "Sacred Flame Demonic Being", while Benimaru was a variant focused on strong and fast physical damage named "Ferocious Berserk Demonic Being", in those times they were called beings, but later evolved into true slimes.
After the pair, Luminous appeared. This little Slime was far tinier than its normal Lower Demonic Beings, named "Lower Sacred Light Being", a very rare variant focused on Light and Holy Elemental Magic. Kireina called her Luminous due to this. She had an angelic and lovable personality, and it is the main healer and light/holy magic user.
And last but not least, there was Aloysius. This slime was a powerful and incredibly interesting variant, she was an Armor Slime! It was a slime that innately had the power to materialize an armor over its slimy body to protect itself. Aloysius had always been quite tomboyish and knight-like since she was summoned and has been the core of their fusion.
And all of these charismatic slimes made up the Slime Family!
