Ryuu told them about the first time Shiro did something outrageous as this, about the first time he vanished, the time when Shiro used [Reset] and came back on his own.
"Leader did something that reckless huh?" Matsuri exclaimed "To quench his thirst for knowledge, yes he did" Ryuu spoke. "Then again, why is he that into knowing everything?" Youko asked "Maybe because he was lacking the destructive po-" Ryuu said but was overlapped by Himari's words "At a young age, he was all about books, he would always burrow his face in books that he would stay up all night reading all of them" she said, when she realized what she said, "At least that's what my father told me" she added trying to hide her embarrassment. "For someone who barely cares, you know a lot, then again, a lot did also happen in the past" Hikaru said with a smug face.
Himari's face became more red then when she is trying to hide her embarrassment. "Can you elaborate [a lot]?" Shiro spoke out of nowhere, they screamed in surprise that Shiro pulled the dagger out on his own, but as for the heirs, they weren't that much surprised. "Why'd you do that?!" Ryuu asked.
Shiro was happy for his colleagues because they were able to fulfil his side mission, but it was time for him to accomplish his own mission, knowing King's name. In the books, there wasn't a single [King] name that was recorded, only in titles, about the kings of the past.
He plunged a dagger to his chest and chanted "Founder's eyes, first spell, [silent chanting] [ghost]" as his soul leave his body, he sees Himari and the others carry him to his room, but he has no time to mess around, in an hour, his soul will go back to his body no matter what he is doing, and so he teleported to the realm [Hell] and went to the royal library to search for books, King told him to move the statue of the founder inside the library to find another library, the uses of the curses, and some ancient spells ton accompany the eyes. When Shiro was in the [reset] state, King was someone who has all of the founder's curses, and as they fought, King used them perfectly. End of flashback. Shiro heads to the founder's statue and pushes it to the side, behind it is a small door that has a staircase which leads to yet another library, one as big as the royal library "Its big right?" King popping out of the blue.
Shiro was startled but regained his composure a little after "If this is big, then why hide it?" he asked "If the founder's magic is leaked, the balance of power in the five kingdoms will fall" King explained. "Then why lead me here?" he asked again "Well, you are like me, one with all five of the founder's curses" King replied in a joyful tone.
In that hour, Shiro was reading all that he could, but to his dissatisfaction, the hour went by in a flash and he has to return to his body, although, but he chanted another spell "[Reset]" he chanted, which sent him to King's space.
"Welcome back, what gives?" King asked "I wanted to ask you who you really are, you don't show up in all of the records, and yet, you have all the founder's curses, you can't be the founder, you guys look different" Shiro argued "No can do, I can't tell you that, not unless you beat me using all of those curses.
"Your magic is boosted in here, even if I used all of my power, it won't scratch you one bit" Shiro protested "Really now? Are you backing down from your regular training?" King mockingly said "Of course not, that's why I will continue" Shiro said in a determined tone.
"There is a fine line between strong and weak. The strong is those who can think of immediate solutions while in war, those who are weak cannot think while battling. For you to be strong, you must know how to fight, and think while fighting" King repeatedly said as he fought Shiro. "What is the significance of those words?" he asked "You just have to find out yourself" King smugly replied.
They continue fighting for 5 days [5 hours] non-stop until King landed his last hit, Shiro enclosed themselves in a barrier wall and as he claimed his victory through a painful experience, we pulls the dagger out himself and asks "Can you elaborate [a lot]?"
When Shiro awoke, they asked him about what he was doing and what was he thinking, Youko, Yuri, Himari, and Tomoe was worried that he may not return, although Himari and Tomoe already saw Shiro come back from the [Reset] state by himself, they were still worried.
As Shiro finishes telling his side of the story, he passed out due to mana exhaustion, the next day, when he woke up, Tomoe was sleeping soundly at the corner of his bed, he get off the bed then places her into it. Leaving the room, Youko and Yuri scolded him for being too reckless and advices him to not do it again. "The member commanding the commander, that's new" he said with a smile.
In the end, only Shiro knew of King's true name, since after he never finished telling his story beyond the barrier, he never told them what happened inside the barrier, nor if he actually pulled the dagger by himself.
He goes to school, then after school comes the reports in the AD-L as Tenryuu.
Going to the AD-L HQ, he teleported using Noro's circle as usual, but the room has changed, there are more Legions hanging on the wall than a few days ago. "Shiro, how's it going? Ayano Yuri reported that you fainted" Noro asked checking his condition "I'm fine, it's just mana exhaustion, nothing I can't handle" he replied. "Good, there are three Legions waiting for you today, one [Shinigami] a gauntlet type, two [Kokyugan] a kusarigama type, and three, [Akatsuki] a dual sword type." Noro explained.
"I can modify them right?" Shiro said with a grim smile.
As Shiro was Modifying the Legions, Shiro heard a voice "Is that a ghoul's bio- weapon?" "Yeah, it is, and I'm modifying this with more bio-weapons" he said without realizing who he is talking too. The voice faded and he focused on his Legion modification process.
The night passed and all three of them have been modified, Tenryuu [Yukimura] is also connected with the other three Legions "[Ryuuketsu]" Shiro said "What is that name?" Youko asked "It's the name of my modified Legion equipment set" he answered.
He went to school just like normal, but he brought [Ryuuketsu] with him. he fused all four cores and made a connection line with the four Legions, with these four, he can shape them as he will, the backlash though is that it will cost some of his mana to shape it. While in school, [Ryuuketsu] is shaped as Shiro's glasses. His glasses have special lenses that makes his vision clearer (N: duh), but now, his eyesight is clear because of the [Founder's eyes] giving him his sight back in perfect shape. So the glasses are now just his Legions and fashion.
Once at HQ, he makes his report and heads home where he finds his squadron training, he heads to his office and prepares the paperwork for the next day "Working hard are you now Shiro?" King said "Damn right, King. Or is it [Lucifer, the founder] now?" he asked, King smirked as he hears his name being spoken for free "You know, to say my name, the other demons would have to pay money" King said "So that's why you hid your name behind [King]?" "In short, yes" King replied.
"I will rely on your curses to take me to the highest points in demon history from today onward" Shiro pleads with a grim smile.
