Issei also replaces the blonde-haired, blue-eyed Jaune Arc, the male protagonist [Jaune] of RWBY, [Issei] having Jaune's signature sword [Crocea Mors] and [Jaune's] limitless Aura and [Jaune's] Semblance of Aura Amp [the ability |Aura Amp| to amplify his |Jaune's| own Aura and that of others, effectively increasing the effects of Aura], but Issei doesn't become a Huntsman, despite [Issei] having skill in weaponry, martial arts and swordplay [unlike Jaune], [Issei] fearing for his [Issei's] life after the incident at the MF Anemone. 

The scene begins when Issei, having his [Issei's] schoolmates at Kuoh spellbound by his [Issei's] explanation of robotics and how the modern world of electronics and smart devices will change humanity during a cultural exchange session, [Issei] is [what happens to Issei] noticed by [who notices Issei] the tomboyish, tough-going and confident, spend-thrift, battle loving, martial arts prodigy, the black-haired, red-eyed, tall, curvaceous and rather buxom Kawakami Momoyo, who [Momoyo] is [who Momoyo is] one of the main heroines of Majikoi and [Momoyo] is [Momoyo] Issei's distant cousin [Momoyo] in the story this scence takes place, along with [Momoyo] replacing [whom Momoyo replaces] Raven Branwen from RWBY, [Momoyo] having Raven's semblance and Momoyo's weapons, in and [who else from Kamakura notices Issei] Momoyo's adoptive little sister, the cheerful, competitive, determined, perseverant but academically disinterested and somewhat ignorant and naive, brown-haired, amber-eyed, short and petite but secretly buxom ookami [wolf] yokai [monster |yokai|] Kawakami Kazuko, who [Kazuko] is [Kazuko] also a major heroine [Kazuko] in Majikoi and [Kazuko] is in fact [Kazuko's true identity in this story] the hot-blooded, quick to act, upbeat and cheerful but also very clingy and naive, brown haired, and brown eyed, short and petite but also somewhat buxom Senomiya Akiho, who [Akiho] is [who Akiho is] one of Robotics; Notes' main heroines [Akiho] and [Akiho/Kazuko] is [Akiho/Kazuko] Kaito's/Issei's half sister [Akiho/Kazuko] in this story, along with [Kazuko] replacing [whom Kazuko replaces in this story] the hyperactive, weapons geek, martial arts prodigy, open and honest but battle eager, naive and somewhat clueless, red-black haired, gray-eyed, short, slender and petite Ruby Rose, the male female protagonist [Ruby] of RWBY, Kazuko having [what Kazuko has] Ruby's mechanical skills, tactical intelligence and [Ruby's] amateur Huntswoman training,  the two [Issei/Kaito and Akiho/Kazuko] being [Issei/Kaito and Akiho/Kazuko] seperated [Issei/Kaito and Akiho/Kazuko] after an accident [the MF Anemone Incident] on a cruise ship that left her [Akiho's/Kazuko's] mother dead was [the accident] discovered to be a attempted assasination by rouge elements of both the US and Russian government by the Japanese government, the two [Kaito and Akiho] only reuniting upon her [Akiho's] adoption by Momoyo's family as Kazuko and [Kaito as Yamato] introducing her [Akiho as Kazuko] as his [Kaito's as Yamato's] 'childhood friend' to his [Kaito's as Yamato's] friends, [Momoyo and Kazuko noticing Issei] with Kazuko noticing how much her [Kazuko's] beloved onii-chan [older brother |older brother (onii-chan)|] Kaito, whom [Kaito] she [Kazuko] has no idea is [Kaito] under a different identity [Hyoudou Issei] after the events of Robotics; Notes, [Kaito] looks like a professor as he [Kaito] gives the lecture, [Kazuko's] eyes becoming dreamy as her [Kazuko's] wolf ears and [Kazuko's] wolf tail emerge in her [Kazuko's] happiness and excitment, [the emergence of Kazuko's wolf features] causing some of the Kuoh students to "ooh" and "aah" at the cute sight [the emergence of Kazuko's wolf features] with some even expressing regret that such a cute country girl [Kazuko] loves the school pervert [Issei], with Momoyo having to [what Momoyo having to do] use her [Momoyo's] martial arts prowess to [Momoyo] keep some Kuoh students from touching her [Momoyo's] adoptive sister's [Kazuko's] canine features. 

Some perceptive Kuoh students also notice that the strange girl [Kazuko] keeps on calling the school pervert [Issei] onii-chan and also note her [Kazuko's] great resemblance to him [Issei], also recognizing the rather infamous female banchou [delinquent leader] of Kawakami [Momoyo] beside her [Kazuko], [Momoyo] acting as a sort of bodyguard to her [Kazuko], along with the hopeful, happy looks in her [Kazuko's] eyes at the sight of him [Issei]. 

As Issei finishes his [Issei's] lecture, drawing a crowd he [Issei] notices the drama in the crowd and [Issei] looks down as soon as the lecture is finished, [Issei] realizing exactly who [Momoyo and Kazuko] have [Momoyo and Kazuko] arrived, [Issei] attempting to flee as soon as the lecture ends, [Issei] not wanting his [Issei's] master, the seductive, sly, cunning and brilliant but also kind and considerate, scarlet-haired, blue-eyed, tall and buxom devil princess Rias Gremory, who [Rias] is [what Rias is] also his [Issei's] English teacher, to find out about his [Issei's] true self [Kaito]. 
 
As he [Issei] attempts to escape from Momoyo and Kazuko, [Issei] not wanting to answer any questions at the moment, he [Issei] stumbles into [the person whom Issei stumbles upon] the calm, reserved, and soft-spoken pale-skinned, gray-haired, yellow-eyed, tall and slender but also buxom and curvaceous Japanese noble heiress Kuki Ageha, who [Ageha] is [Ageha] a major supporting character [Ageha] in Majikoi and [Ageha] is [Ageha] Momoyo's major rival [Aghea], who [Ageha] is [Aghea] the current head [Aghea] of [the organization Aghea heads] the world-spanning, electronics, manufacturing and financial giant of the Kuki Zaibatsu [Kuki Megacorp |Kuki Zaibatsu|] and [Aghea] replaces [the character Aghea replaces] Winter Schnee from RWBY, [Aghea] having [Winter's] Semblance and [Winter's] abilities in addition to her [Aghea's] own formidable martial arts skills and [the other person whom Issei stumbles into apart from Ageha] her [Aghea's] younger sister, the gray-haired, pink-eyed, short, petite and slender, secretly buxom refined, mature and highly intellectual but also shy, reserved and childish Kuki Monshiro, who [Monshiro] goes by the public alias of [the public identity Monshiro uses in this scence] Yukifune Airi, a petite girl [Airi] with [Airi's chararistics] light skin, long, grey hair tied with a black bow with [Airi's personality]  cheerful, playful and innocent but also sad and lonely, who [Airi] plays a major role in the events of Robotics; Notes, [Monshiro] also [what Monshiro also does] replacing [the character Monshiro replaces] Weiss Schnee from RWBY, [Monshiro] having [what Monshiro has] Weiss' Semblance and Weiss' weapon in addition to pieces of Weiss' arrogant and cocky personality. 

The Kuki's are Kaito's distant paternal relatives in the story the scene comes in, [Kaito] receiving a quite extravagant allowance from the Kuki sisters' [Monshiro's and Aghea's] father, which [the allowance] he [Kaito] mostly saves and invests, [Kaito's financial wisdom] making him [Kaito] quite rich himself although he [Kaito] is [Kaito] clueless about this, along with the crush both sisters [Aghea and Monshiro] have on him [Kaito], which [Aghea's and Monshiro's shared crush on Kaito] results on the older Kuki sister [Aghea] shoving his [Issei's] head into her [Aghea's] quite large breasts as Monshiro clings to him [Issei], causing Momoyo and Kazuko to [Momoyo and Kazuko] get jealous. 

Aghea eventually releases him [Issei] from her [Aghea's] grasp, causing him [Issei] to blush, although Monshiro soon also [Monshiro] clings to him [Issei] before [Monshiro] also letting him [Issei] go, which allows him [Issei] to [Issei] finally breath. As the Kuki sisters let go of him [Issei], he [Issei] thinks back to the events of Robotics; Notes, where his [Kaito's] beloved little sisters' [Akiho's] supposedly insane plans of creating a fully functional, anime and video game style humanoid mecha [Super GunBuild-1] ended up actually being working out in the end, with the mech [Super GunBuild-1] being useful in the fight against the traitorous, white haired, blue-eyed, tall and slender megalomanical Okinawan mad scientist Kimijima Kō and his [Kō's] elite mafia group masters, the Commitee of 300, which resulted in him [Kaito] learning a strange, hidden truth about the Kukis - the youngest daughter of the family [the Kukis] is imprinited with the magical and technical knowledge accumulated by the clan [the Kukis] throught the long centuries, which was the basis of the infamous Necromonion from Lovecraft's works. 

The current "Necromonion" is Monshiro, who [Monshiro] awakened her [Monshiro's] abilities [as the current "Necromonion"] when [Monshiro] was [Monshiro] almost possesed by [Kō's] AI ghost, which failed and instead Monshiro ended up being able to split her [Monshiro's] conciousness between the real and the virtual world, her [Monshiro's] power transforming Super GunBuild-1 into a fully functional Gundam style mecha that [Super GunBuild-1] was [Super GunBuild-1] able to take on the horde of Commitee of 300 operatives and [Commitee of 300] mafia and rouge intelligence agency contractors descending upon Okinawa's space station to start the apocalypse as he [Kaito] used his [Kaito's] skills in playing Gun-Ballad to pilot it [Super GunBuild-1] while Akiho was [Akiho] pressed up against his [Kaito's] body with Monshiro, who [Monshiro] was [Monshiro] acting as the unit's [Super GunBuild-1's] guilding AI at the time, pouted in jealousy.

Inside Issei's head, the Red Dragon Emperor inside his [Issei's] Boosted Gear, Ddraig can't stop laughing, [Ddraig] having the most fun he [Ddraig] has [Ddraig] had in centuries. As the Kamakura girls [Momoyo, Kazuko, Aghea and Monshiro] prepare to face off over his [Kaito's] love, the blonde-haired, green-eyed, anti-social, blatantly perverted and obsessive but focused and determined half-Deutsche [German] Frau [Lady] Kōjirō Adelheild, who [Adelheild] is a rather famous and outspoken tall, slender and buxom noble heiress of good Japanese and Deutsche bloodlines and [Adelheild] has [Adelheild] gathered controversy for her [Adelheild] eccentric and [Adelheild] is [Adelheild] secretly a skilled and rather good programmer and gray hat hacker who [Adelheild] created the rather infamous mecha fighting game Kill-Ballad that Kaito is [Kaito] addicted to [Killballad], [Adelheild] having come from her [Adelheild's] current home in Okinawa to [Adelheild] check up on her [Adelheild's] one true love [Kaito], [Adelheild] decides to join in on the fun, [Adelheild] causing even more surprise from the crowd of Kuoh students as she [Adelheild] reminds him [Issei] 

[Adelheild] seeing the fight about to start between the girls of Kawakami [Momoyo, Kazuko, Aghea and Monshiro] over him [Issei] decides to end the whole debate by suggesting that all of them [Adelheild, Momoyo, Kazuko, Aghea and Monshiro] share him [Issei] as his [Issei's] wives, which [Adelheild's suggestion of a harem] causes gasps of shock and some of disgust, wolf-whistles from some of the more perverted guys and plenty of videolight from the high-priced cellphones of the Kuoh students along with the occasional faint of shock as the girls of Kawakami [Momoyo, Kazuko, Aghea and Monshiro] calm down and [Momoyo, Kazuko, Aghea and Monshiro] along with Adelheild, carry him [Issei] away for a combined date with all five of them [Adelheild, Momoyo, Kazuko, Aghea and Monshiro] and also to find out why he [Kaito] is now in Kyoto, the students of Kuoh being silent as they [Momoyo, Kazuko, Aghea and Monshiro along with Adelheild] carry him [Issei] away, with one student commenting later that this whole things feels like something out of a eroge dating sim visual novel or a perverted harem anime. 

Meanwhile, the black-haired, red-eyed pale-skinned, tall and slender Orimura Ichika, who [Ichika] never discovered that he [Ichika] could pilot an IS and [Ichika] was raised by his [Ichika's] relatives in rural Jamaica instead of his [Ichika's] older sister Chifuyu, [Ichika] looks at the situation [the girls leaving with Issei] from the scope of a sniper rifle from a hidden location, [Ichika] having [what happens to Ichika] become a militant fascist revolutionary [Ichika] fighting against corrupt corporations, greedy communists and expansive government officials while [Ichika] posing as a rather popular and controversal dancehall artiste named Alkaline, who [Alkaline] is [Alkaline] known for his [Alkaline's] sexually explict, raunchy, gang violence and action supporting, hardcore ghetto supporting music and [Alkaline] is [Alkaline] infamous for wearing a Guy Fawkes Mask during his [Alkaline's] performances, [Alkaline] having a rather strong gang/fanbase called the Vendetta Crew that [the Vendetta Crew] has [the Vendetta Crew] essentially seized control of the Jamaican underworld from local terrrorist and drug cartel factions in Jamaica, [Ichika] laughing to himself [Ichika] and [Ichika] muttering that the time for 'justice' [launching a terror attack on the Kukis during the date with Issei] is right before [Ichika] leaving in order to [Ichika] summon a few of his [Ichika's] Vendetta Crew minions, putting on a Guy Fawkes mask as he [Ichika] does so. 

Masking their [Alkaline's and the Vendetta Crew's] attack on the Kukis as a hit on a rival Jamaican terrorist, the crew of mayhem [Alkaline and the Vendetta Crew] are almost successful, managing to take out the protection detail due to the huge amount of heavy weaponry they [Alkaline and the Vendetta Crew] managed to slip into the country [Japan], but [Alkaline and the Vendetta Crew] ultimately failing due to Rias and the rest of her [Rias'] peerage arriving at the same place they [Alkaline and the Vendetta Crew] attack and [Rias and the Gremory peerage] decimating the terrorists, Alkaline barely escaping and the Vendetta Crew minions being slaughtered as their guns prove worthless against the peerage's supernatural powers. Issei finds himself [Issei] smothered by the girls from Okinawa and Kawakami, [Issei] unable to get away. Rias, upon seeing this, [Rias] comments that she [Rias] now understands why he [Issei] is [Issei] afraid to go any further in the relationship he [Issei] has with her [Rias'] and the other girls of the Occult Research Club, but she [Rias] is his [Issei's] first wife whom [Rias] he [Issei] must be the first to impregnate during the honeymoon and that he [Issei] must explain everything to her [Rias] in the privacy of the ORC clubhouse.
