But letting Eevee evolve requires respecting their opinions.
We'll put aside the opinions of those Eevee who have already evolved.
Even though Naoki wants the remaining Eevee to evolve into forms not yet owned on the ranch, before taking action, he needs to ask for their opinions thoroughly.
Naoki focused his mind and, once the Eevee had played outside and gotten tired, he gathered all the Eevee in the living room.
Then, Naoki took out the book that recorded all Eevee attributes and introduced the potential evolution forms to the Eevee.
Nine Eevee squatted in a line on the floor, with only Glaceon and Umbreon looking neutral, while the others were full of curiosity.
"Ahem," Naoki cleared his throat, drawing all Eevee's attention to himself.
Koraidon brought out a small blackboard, and Naoki cut out images from the book and categorized them on it.
"Initially, I didn't plan on telling you about this now, but three mischievous Eevee accidentally ran into my Treasure Vault and touched the Evolution Stones I stored there, evolving ahead of time," Naoki explained.
He originally planned to let them evolve when they were older, at least one or two years old.
Upon hearing this, the other Eevee glanced at the middle, where stood Flareon, Jolteon, and Vaporeon.
"Eee..."
The trio of fire, water, and lightning showed embarrassed expressions, stuck out their tongues, and tried to Charm Naoki into letting them off the hook.
"Eee-vee~"
Naoki sighed helplessly, then refocused on the main topic.
"Eevee, I'm talking about you." Naoki swept his gaze over the Eevee before him: "Every Eevee has infinite evolution possibilities."
"Evolution is the process of becoming stronger, just like Flareon, Jolteon, and Vaporeon."
"Currently, humans have discovered eight Eevee evolution forms."
The Eevee listened attentively.
Naoki tapped the pictures on the blackboard: "First, let me introduce Flareon, like this one here."
Saying this, Naoki pointed to Flareon in the group.
"Flareon, as the name suggests, has the ability to control fire, can spit high-temperature flames from its mouth to attack, and can roast berries with fire."
"Eee!" Under the gaze of all the Eevee, Flareon nodded repeatedly, indicating that Naoki was right.
To prove it, Flareon took a deep breath and released a small flame.
The flame hit the carpet, instantly setting the woolen carpet on fire.
Naoki: "!!!"
"Flareon!" Naoki felt his breath tighten.
Seeing the burning carpet, Flareon realized it had made a mistake, "Eee..."
Fortunately, Vaporeon used Water Gun in time to extinguish the flame.
Looking at the burned carpet, Naoki blackened face issued a command to the Pokémon: "No one is allowed to use moves at home from now on!"
"Eee, Eevee!" Already guilty, Flareon quickly nodded, indicating it understood.
"Since it's your first time, and I hadn't taught this before, I'll let it go this time. But you absolutely can't do it next time, understand?"
"Eee!"
Naoki then continued with the lesson: "I believe you all understand Flareon's abilities, next, let me introduce Vaporeon."
Unlike the lively, impulsive Flareon, the evolved Vaporeon became gentle, like flowing water.
Upon hearing its introduction, Vaporeon happily wagged its tail.
"Eevee evolves into Vaporeon, losing its fur but gaining the ability to live in water, freely control water, and flexibly use Water Gun to attack opponents. In life, it can also water berry trees and extinguish fires."
The Eevee curiously looked at Vaporeon, some seemed interested, while others showed less interest.
"Next, I'm introducing Glaceon." Naoki turned his gaze to Glaceon.
"Glaceon, the fresh snow Pokémon, uses ice and snow powers to attack. In summer, staying near Glaceon means you don't need to worry about the heat or sunstroke! In short, Glaceon is also a reliable Eevee."
Glaceon didn't speak but nodded slightly, appreciating Naoki's special introduction!
"Now, Jolteon, evolved through the Thunder Stone. It can use strong electricity to paralyze opponents, demonstrating great strength."
Naoki looked at Jolteon; the Pokédex says Jolteon tends to be neurotic, making bonding difficult for Trainers.
Yet, Jolteon was quite gentle, perhaps due to Naoki hatching it from an egg.
Jolteon even voluntarily gathered electricity, showcasing its power for the other Eevee to see more clearly.
"Lastly, Umbreon," Naoki continued: "Umbreon, evolved under the moonlight, is a nocturnal Pokémon, most active under the moonlit late night."
