Later, a meeting is held at the conference room where everyone is discussing the upcoming Secret Athletic Festival, an annual event where students from all three school-years participate in order to improve their mercenary skills. Out of all people from their perspective class year however, J.D. Makishima boasts the Third Years as the winner to the event every year while belittles other students from the First Years and the Second Years[Notes 7], especially towards Mortio and Mammon who he views as losers who they refuse to be beaten by.[Notes 8] Mytra, who sees J.D. touches her "property", doesn't take his insult to Morito lightly and mocks him as a Gorilla, instantly igniting the fierce rivalry between the Second Years and the Third Years[Notes 9].

To the teachers' surprise, Morito is seen unusually calm while saying that, according to the flyer, faculty members are also welcomed to participate the event. Interested by this idea, Rena approves the teachers' participation into this event and proposes a tournament style battle where she welcomes anyone (especially Hibana and Gisele) to beat her, seemly boosting everyone's spirits. Rena also invites Kotonoha to participate the event as she yearns to see her power after hearing her rumors. Unable to bear Rena's optimism, Futaba appears and accepts her invitation into the Secret Athletic Festival on Kotonoha's behalf.

Faculty Team vs First Years Team

On the day of the event before the tournament, Elen explains the first match would be the Capture-the-Flag match. Ann begins the match by telling everyone to have fun. As the respective team captains picks their draws, the decisions these decision of these matches are made: First Years Team and Faculty Team are the first team to compete each other in the first match, while Second Years Team and the Thrid Years Team are next.

Before the match, Elena is called by a senior faculty member in a discussion to the plan, which she initially become skeptical until Ann gives her permission to this plan.

In spite of the heated battle between two teams for the flag, a ceasefire announcement is made that ends the match as Rena captures the flag effortlessly, leading to Faculty Team's victory in this first round.

Away from the scene, Ann and Jin confront Mammon who reveals her disguise after she is being discovered. When Ann asks her if she will participate the events, Mammon replies that she wasn't sure but claims that the first round should be easy and bet that they will be facing the Faculty Team in the finals. Ann warns Mammon not to underestimate the Third Years Team however, as she claims that they have the Student Council as their aid.

Second Years Team vs Third Year Team

Thrid Years Team meanwhile reports the Faculty Team's performance to the Student Council president Minoru Shishio. When J.D. reassures that his team will be prevailed over their "spineless" opponents, Minoru declares that the Student Council will not participate the first round while leaving the battle to the Third Years Team, though he also adds that he wouldn't mind destroy to destroy the Second Years Team by himself[1].

Elsewhere, Gisele discusses a plan with her fellow Second Years students and reminds them how they are looked down by the Third Years students, garnering everyone's aggravation. When J.D. tells his comrades that they only need sheer force for the victory, Gisele on the other hand tells everyone that they will beat the Third Years Team with "No Strategy". Gisele's plan and determination garners Morito's impression. Futaba, who is hiding behind a tree while witnessing the Second Years Team determination, especially both Gisele Sisters and Saiga Sisters while thinking about Rena, also vows to win for Kotonoha's sake. Under Elena's declaration, the match between the two teams begin.

Manga Ch 42 Victorie

Hamelin Sisters defeat J.D..

As the Second Years Team are winning, J.D. had to call his team to fall back. The Student Council however-especially Minoru-doesn't take the team's poor performances lightly as the latter reminds J.D. that (s)he will not tolerate failure and (especially) liars. So, J.D. desperately charges towards the Second Years Team and grabbing Gisele via a bearhug, even though he is shot by the Second Years Team's paint bullet, which Gisele states as the game's violation. Fortunately, with the help from Mytra and her fellow Second Years Students (Saiga Sisters and Kyril), Gisele manages to break free and defeats J.D. by putting paint bullet to his face, leaving the Student Council as their final opponent. However, Minoru tells the Third Years Team to leave while he handling the Second Years Team alone.

In this confrontation, Minoru gloats that he will not compromise with mercenaries who he belittles as a "barbaric bunch" and claims himself to be "beyond special" and so powerful that he doesn't need anybody's protection. Both Morito and Mammon see the light emitting from afar, much to their concern as Morito suspects that light as the power of Numerology, a mysterious power that rumored to be used by Simon Beiler to kill the two Master Ranked Mercenaries. While worrying that whoever has that kind of power will ought to be unstoppable[2], adding that any contact between Numerology and Dead language will create an unlikely destruction, Morito leaves the post to Mamon and rushes to the scene.

Back to the battle, with the Numerology as "his" advantage, Minoru easily beat the Second Years Team effortlessly, leaving Futaba is the only one left. The battle quickly ensues as Kotonoha changes various personas (except Mutsuba) in order to counter Minoru's power. Minoru however manages to subdue Futaba with his powers by sealing her numbers. There, Minoru tells Futaba that he knows everything about her while proposes her to be his "girlfriend" to live his "ideal" world. Even when Morito reaches to the scene just in time, Minoru ignores him and kisses Futaba right in front of former. Felling sullied for her stolen first kiss by Minoru with Morito (also Rena) watching from the sidelines, Futaba immediately transforms into Nanoha and vows to kill Minoru despite this only fuels "his" desire for her even more.

Meanwhile, Rena, who is watching the battle from afar, is thinking about putting the match off until she sees Simon sitting besides her. When Rena asks his intention, Simon replies that he is not alone[3] and explains that he came all the way from the United States to watch a clash between Numerology and Dead Language. Morito manages to break them up before however, much to Simon's dismay, and also calm Nanoha down by telling her about person she liked and the real experience of falling in love, prompts Nanoha to blush red and changes to Yotsuba. Morito then fights Minoru where he defeats "h(er)im" by temporarily blinds [Notes 10] him with a flash grenade and punch him on the ground, only for him to realize that Minoru is actually a girl[Notes 11] . While that going on, the Second Years Team already won when Mytra-who wasn't even involved in that battle under Gisele's instructions-manage to catch the flag, meaning the Second Years Team advances to the finals.

Child Room Seven

Rena and Child Room's Mercenaries (except Sis).

Back to Simon who apparently dissapointed by the "boring" outcome, he insists the event must go on by having Rena to have him and his "friends" participate the Secret Athlete Event as well, much to Rena's confusion. To Rena's surprise however, Simon's friends are none other than the Child Room's Master Rank Mercenaries that consists of Chico, Sol, Brad, Sayuri and Alex. What Rena little anticipated is Simon then uses his Numerology to awaken "someone" within her body, which later revealed by Simon as Juri, also known as Sis the #13 Master Ranked Mercenary that takes over Rena's body and consciousness.

During their preparations, Gisele plan to put their base in defense mode while and dispatches their Offense Squad-which comprise of Morito, Mammon, Hibana, Mizuki and Kyril- to take the opponent flag. Despite his skepticism, Kyril reluctantly bring Morito and Mammon along as long they are not "causing trouble". On the Faculty Team's side, Elena announces that this battle's finals would challenging because they had to face Morito, with Ann adds that she forbids anyone from running away."Rena" however suggests to have her hold off Morito alone as she knows Morito's weakness, something that not even exceeds his past proteges's knowledge. This leaves Elena little choice but to leave Morito to "Rena's" plans without knowing her menacing intentions.

As the match begins, Second Years Team's Assault Team confronts "Rena" where Kyril and Saiga Sisters as her opponents, with one-sided from Hibana's desire to avenge her lost from their first encounter. However, "Rena" easily beats the team as she breaks Kyril's nose, punching Mizuki and nearly kill Hibana only to be interrupted by Morito. The two fight briefly where Morito tears off "Rena"'s bandages and recognizes her to be Juri, specifically after seeing her Number II on her chest which Futaba assumes that Rena also have Multiple Personalities.

In a surprising turn however, Morito is now able to read Juri's mind telepathically and tells her that he knows the Super Tuning all too well-including its own weaknesses-and instead tells her to use that power to read his heart in the past and learn about Mieko's real death. It turns out Mieko was suffering her depression after hearing a painful voices from her society that have shunned her as a nuisance and a mere "tool", despite Morito was the only exception; to make matters worse, she also worrying that her own power will further bring Rena to an unwanted burden, especially after her Third Eye showing her daughter's true feelings.
