Ding! 

[You have accessed your Class Trial Special Privilege: [Unique Familiar Evolution]. The current Familiars capable of accessing this Privilege Reward are [Violet], [Snow], and [Shiro]. Those unable are not qualified.] 

[Do you wish to evolve your Familiars using the Special Privilege? No additional Materials are needed, but the more you add, the stronger the evolution could become, as long as the materials are compatible.] 

[Yes] [No] 

After selecting [Yes], the evolution began. 

[The Class Trial Special Privilege: [Unique Familiar Evolution] has started!] 

[The order of the Evolutions will be from oldest to newest Familiar, starting with [Violet], then continuing with [Snow], and ending with [Shiro]. After evolving, Familiars will ascend into stronger forms to assist you further on your adventure.] 

[Materials offered during the evolution process will be absorbed automatically by the Familiar if they are compatible with their Elemental Affinities and Species.] 

[Violet]’s Evolution has started! Please add as many Materials as you have prepared before the Evolution ends.] 

As the messages indicated, Violet was the first to evolve. He absorbed all the materials I had prepared for him, along with some of Sepa’s Divine Essence. This not only enhanced the evolution but also served as a material, just as I had envisioned. 

FLUOSH! 

He evolved in his base form, which was the size of a car. He usually shrank to sleep in bed with me, but as his evolution began, his car-sized form expanded. He grew and grew and grew. 

And grew even more! 

“Holy…! How big are you going to get, Violet?!” 

When his evolution finished, Violet was larger than a bus, bulky and powerful. His exoskeleton, once purple and black, now gleamed with a metallic sheen, blending gold, purple, and red, with red and purple jewels embedded in his body. 

His scythes were longer and sharper, and he had gained a second pair. Sharp spikes lined his long body to better defend against attacks from blind spots. 

His head had grown larger, resembling his mother’s, with enormous eyes glowing with yellow light, seemingly made of crystals. Several antennae and sharp horns adorned his head, alongside sharp jaws and fangs. 

“KRIEEEEHH!” 

His roar echoed through all of Purgatory. I was grateful I hadn’t let him evolve outside, or his roar would have woken everyone sleeping at this hour. 

His Aura radiated Divine Essence, strikingly similar to Sepa’s. He had not only evolved into a powerful being but had also attuned more closely to Sepa herself. 

He was becoming her perfect Avatar. 

Ding! 

[Congratulations! Your Familiar [Violet] has Evolved from [Abyssal Demonic Centipede (C+++ Rank)] into [Celestial Martial Golden Centipede (A+++ Rank)]!] 

[All of Violet’s Stats have increased greatly!] 

[Violet] has learned the following new Skills: [Celestial Martial Golden Exoskeleton Armor (A): Lv1] [Celestial Light Ki Materialization (A): Lv1] [Holy Celestial Centipede Palace Domain (A): Lv1]!] 

[Violet] has gained the Privilege: [Millipede Constellation Divine Avatar (S Rank Privilege)]!] 

[Violet] has gained the Titles: [Celestial Martial Beast] and [Sepa’s Divine Avatar]!] 

[Violet]’s Max Level Cap has increased to Level 300!] 

[Violet] has developed a Physique!] 

[Violet] has developed a Martial Core!] 

[Violet] has Unlocked the [KI] and [SOUL] Stats!] 

“Wait, what?! No way! You actually became her vessel now?! Wait, how does that even work? Did you do that, Sepa?” I wondered. 

“I didn’t do anything!” Sepa complained angrily. 

“Well, whatever, this might be useful. Well done, Violet! You’ve really grown today!” I said happily, patting his head. “But I hope you can return to your original size, or smaller if possible.” 

“Krieeeh…” he sighed with disappointment. 

Right after Violet finished evolving, Snow began his evolution. He grew significantly larger, though not as massive as Violet, reaching the size of his mother, who was already a gigantic wolf. 

His fur remained mostly white, but patches of blue fur appeared on his body, and several sharp, ice crystal-like horns sprouted across it. These were a special kind of ice that didn’t melt, part of his biology. 

A glowing blue crystal appeared in his forehead, shining brightly and emanating a potent aura of spiritual ice energy and Yin Ki. 

His eyes glowed with golden and blue light, and he appeared more mature. Despite being a huge wolf, he retained that “puppy” aura, but now he seemed fully adult, his gaze reflecting that maturity. 

“Awoooooo!” 

As he howled, new notifications appeared. 

Ding! 

[Congratulations! Your Familiar [Snow] has Evolved from [Giant Horned Glacial Wolf (D+++ Rank)] into [Spiritual Martial Glacial Yin Wolf (A+++ Rank)]!] 

[All of Snow’s Stats have increased greatly!] 

[Snow] has learned the following new Skills: [Divine Soul-Freezing Yin Claws (A): Lv1] [Ghostly Glacial Wolf Pack Summon (A): Lv1] [Ultimate Frost Domain (A): Lv1]!] 

[Snow] has gained the Privilege: [Divine Martial Beast Guardian Of Niflheim (S Rank Privilege)]!] 

[Snow] has gained the Title: [Yin Martial Beast]!] 

[Snow]’s Max Level Cap has increased to Level 300!] 

[Snow]’s Physique has grown stronger!] 

[Snow] has developed a Martial Core!] 

[Snow] has Unlocked the [KI] and [SOUL] Stats!] 

Snow’s Aura erupted, instantly freezing his surroundings. Snow fell from the skies the moment his evolution completed. His Aura had grown vastly larger and stronger, as had his stats. Those three new Skills and that Privilege showed me he didn’t need additional divine power from a Constellation or anything else. 

“Well done, Snow! You’ve grown much stronger now, and I bet you want to let Baihe ride you again, don’t you? It seems your abilities have evolved to reflect that bond you share with her,” I nodded. 

“Woof!” Snow seemed to agree. 

An intriguing connection between him and Baihe had formed earlier, and it appeared that when they worked together, they could grow stronger. 

Lastly, Shiro was about to complete their evolution. I had already added all the materials, and the final component was Bastet’s Divine Power, added in smaller quantities. 

Her Divine Power resembled golden sand crystals that glowed during Shiro’s evolution. A brilliant white and golden light surged, followed by an eruption of energy. Shiro’s size doubled, reaching that of a medium-sized dog. 

Wow, Shiro was really small, huh?
