While Takeru's world was thriving, in other parallel worlds, people were also diligently completing their missions.
For instance, Yui, Ui, Mio, and Tsumugi were grouped together. None knew the plot, so initially, having no money, they were taken in by Aria.
Later, when Night Raid attacked the family, the four directly confronted them. Hearing from Akame and the others about the darkness of Aria's family and the empire's corruption, the four exchanged glances and chose to join Night Raid.
Because their abilities were quite unique, even without Teigus, Akame and the others accepted them.
Within Night Raid, the four trained diligently daily and gradually began participating in operations. Although their strength was among the lowest in Night Raid due to lacking Teigus, their magic contributed significantly. Ui's assassination skills were even stronger than most.
With their addition, Night Raid's manpower increased. During the battle with Zanku, Yui detected him using Observation Haki and, cooperating with Akame, eliminated him.
They confiscated the Teigu, Spectator. Tsumugi, curious about this eye-like Teigu and having no aversion to it, had a wavelength highly compatible with it. The group entrusted the Teigu to her.
After obtaining Spectator, Tsumugi's strength greatly increased, and she worked well with Mine.
During the subsequent battle with Seryu, having Ui and Tsumugi present resulted in Seryu being thoroughly beaten.
They confiscated Seryu's Teigu. After bringing Koro back to the secret base, Yui and Koro took a liking to each other. Thus, Yui also became a Teigu user.
In the battle with the Three Beasts, they acquired three more Teigus. Mio and Ui respectively obtained Teigus compatible with them: Military Music Dream: Scream and Water Dragon Possession: Black Marlin.
Although Mio wasn't very skilled with the flute initially, she quickly learned. It can be seen that Mio had great talent for musical instruments.
With Teigus, the four's strength increased substantially. While Ui couldn't create vast amounts of liquid from nothing, her Item Storage allowed her to store water in advance for use during combat.
…
Aside from the smoothly progressing four, Yukino, Rikka, Hachiman, and Yuta also fared reasonably well. Initially, they earned some gold through unique abilities, settled in the capital, and thus missed the early plot.
After gaining some understanding of the world, they quickly recognized the empire's darkness. Well-educated, they were unwilling to serve the empire.
They lived normally, hunting Danger Beasts in the wild for income while helping people in the slums as much as possible.
Their actions soon caught the attention of Leone, who frequently visited the slums. After several encounters, Leone extended an invitation to them.
Through Leone, they gained deeper insight into the empire's corruption. After consideration, Yukino and Hachiman analyzed that joining Night Raid might yield a higher evaluation score. Thus, they decided to join Night Raid.
Although they joined later, through their efforts, they participated in numerous events and inadvertently prevented Sheele and Bulat's deaths.
Beyond that, their presence didn't drastically alter the world's progression. Things proceeded mostly as usual. The empire still formed the Jaegers, and they learned about Esdeath and Great General Budo, the empire's strongest.
After some discussion, they decided to avoid confrontations with them whenever possible.
Later, they encountered Dr. Stylish. After a fierce battle, they eliminated him. With Yukino and the others' assistance, they faced fewer difficulties during the fight.
…
In the blink of an eye, over twenty days passed. Under Takeru's governance, the empire stabilized, both internally and externally. Takeru delegated tasks, uncovering many talented individuals.
Some former officials were allowed to retire. Due to extensive purges, the noble class had significant vacancies, which was beneficial.
Previously, nobles and commoners seemed eternally divided, but now, there was a chance for integration.
Takeru established numerous schools, including military academies and regular schools, allowing commoners to access education and upward mobility.
As for the Revolutionary Army, as expected, some higher-ups had long since changed, unwilling to relinquish hard-won power.
After repeated failed negotiations, led by Najenda, former Night Raid's members and the Jaegers assassinated these leaders and disbanded the Revolutionary Army.
After resolving everything, Takeru rarely appeared publicly. Instead, he spent his days with Esdeath, Akame, and others, traveling, training, and hunting Danger Beasts.
During this time, Takeru included them all in his harem. Given the world's societal norms and Takeru's status as Emperor, they had no objections to becoming his consorts.
In a grand ceremony witnessed by the entire nation, Takeru married Esdeath, Leone, Mine, Akame, Kurome, Sheele, and Chelsea as his consorts.
Only Najenda, due to specific reasons, didn't develop deep romantic feelings with Takeru.
As for Chelsea, serving as Takeru's personal secretary for a period, her initial curiosity about him inevitably turned into affection for his charm.
As the two-month deadline approached, the women seemed to sense something.
Upon inquiry, they learned Takeru would soon depart alone for someplace and would take time to return.
Moreover, afterward, the time Takeru could spend with them would decrease, saddening them.
Thus, they cherished their time with Takeru even more. In the remaining time, Takeru also collected several Teigus.
Takeru now possessed five Teigus: Shambhala, Black Marlin, Glorious Hands of God: Perfector, Thunder God's Rage: Adramelech, and Great Tremor: Heavy Pressure.
Great Tremor: Heavy Pressure is a microphone-type Teigu. Sound emitted through it transforms into ultrasonic waves, pulverizing enemies. Its secret technique is [Nasty Sound].
This Teigu was confiscated from the Revolutionary Army. Takeru didn't confiscate other Teigus distributed to his companions. Even though Takeru would leave, he planned to return to this world later.
Takeru didn't want the world to descend into chaos upon his return. Most importantly, he didn't want Esdeath, Akame, or the others to suffer any harm.
In the final days, aside from occasionally returning to the palace, Takeru and the others spent time in the wilderness, enjoying the world's beauty and the sense of accomplishment of hunting and taming Danger Beasts.
Additionally, Takeru taught them Armament Haki and Observation Haki.
Though they hadn't mastered them yet, Leone showed great talent for Armament Haki, especially in her beastified form. She would likely gain control soon.
Esdeath and Mine showed particular aptitude for Observation Haki.
As for Akame, Sheele, and others, they progressed steadily in both abilities, showing no lack of talent.
Furthermore, when the foreign tribes invaded the capital again, Takeru led Esdeath, Akame, and others to suppress them militarily.
Esdeath, needless to say, unleashed terrifying ice, causing countless casualties. Takeru's [Poison Dragons] also caused mass deaths. Takeru also equipped Adramelech, which is confiscated from Great General Budo.
Takeru developed several skills with it: [Thunder Dragon's Jaw], [Thunderclap], [Thunderburst], and the Teigu's inherent ability, [Solid Shooter].
There were also support skills like [Godspeed] and [Lightning Armor]. Godspeed used electricity to forcibly exceed physical limits, which took inspiration from Killua's ability.
Lightning Armor covered his body with Aura and lightning, activating the physique, enhancing attack, defense, and speed.
However, since the Teigu itself was armor-type, Lightning Armor was developed but rarely used.
