Write an drama-filled,  dialogue-filled and exposition-filled narrative in the form of a crossover fanfic between Black Bullet, My Hero Academia and Date a Live which occurs after the elimination of the deadly parasites that have risen to the top of the food chain in the past 10 years, who infect their hosts and turn said hosts into monsters and also give them superhuman abilities and enemy to all mankind known as the Gastrea from Black Bullet and the subsequent covert ending to the Initator, which refers to the young girls who were infected with the Gastrea virus but didn't mutate into monsters, gaining animalistic traits but keeping their human mind and reasoning known as Cursed Children from Black Bullet being paired with an older human mercenary known as a Promoter from Black Bullet after the elimination of the Gastrea by the world powers in this story, with many Promoters and Initators shifting to the mercenary business after the end of the Gastrea.

In this story, Japan didn't fall to a communist revolution after the emergence of the supernatural powers with sources in human mutation and evolution, being sorted into multiple categories but with users of these powers only developing one ability and are thus unable to achieve any other through natural means known as Quirks from My Hero Academia in the world like in canon My Hero Academia before the events of canon My Hero Academia started in this story, but instead Buddhist supremacists, Japanese nationalists, traditionalists and feudalists loyal to the memory of the Tokugawa shogunate and the samurai formed an unlikely coalition with social Democrats and monarchists who supported the reigning Japanese imperial family, the supposedly Shinto-pantheon descended, Japanese Imperial House of Great Yamato/Minamoto dynasty to hold back bandit, organised crime and growing Quirk liberation and Quirk freedom movements in Japan, more specifically the Quirk supremacist, radical communist, anti normal human, eugenicist terrorist group turned secret society/paramilitary organization and think tank along with large, powerful villain organization that follows the philosophy that the free usage of Quirks is a basic human right and emphasizes liberation over regulation, the infamous Meta Liberation Army from My Hero Academia, with the Meta Liberation Army's founder and infamous first leader, the brown-haired, dark-brown eyed, tall and slender first generation Quirk user turned Quirk freedom advocate and terrorist Yotsubashi Chikara, later [Chikara] known as "Destro", [Destro in this timeline] being [Destro in this timeline] killed by a Japanese Buddhist supremacist when he [Destro in this timeline] attempts to storm the meeting place of the Japanese national legislature, composed of a lower house known as the House of Representatives, and an upper house, known as the House of Councilors, with both houses being elected under a parallel voting system and having the responsibility of nominating the Japanese Prime Minister from the winning party of Japan's democratic national elections in addition to passing laws, the National Diet, the National Diet Building in Tokyo, [Destro storming the National Diet Building] with some of his [Destro's] MLA cultists.

The traditionalist-progressive coalition in Japan that emerges after the emergence of Quirks in this story then manages to get the approval of the National Diet and the then Japanese Prime Minister due to the defence of the National Diet building from the MLA cultists, with the retreat of the Americans from Asia after the emergence of Quirks in this story and the collapse of the post-Soviet Russian Federation and the fascist People's Republic of China ruling over the China region since 1949 to national liberation movements, pro democracy revolutions and dissident movements within these regions leading revolts against the Russian Federation's ruling crypto-communist, Neo-Trotskyist United Russia Party and the PRC's de jure Marxist-Leninist, anti-Stalinist communist but de facto Han supremacist, Han nationalist and Han imperialist Chinese Communist Party, [The traditionalist-progressive coalition in Japan that emerges after the emergence of Quirks in this story exploiting the withdrawal of the USA and the collapse of both Russia and China after the emergence of Quirks in this story] to gain the support of the National Diet to restore the pre-1947 Imperial House of Great Yamato/Minamoto dynasty-ruled unitary parliamentary absolute royal democratic Imperial monarchy of the Great Japanese Empire as the government of Japan, albeit under the feudal hereditary military government of the side branch of the Imperial House of Great Yamato/Minamoto dynasty, the Tokugawa clan-ruled Tokugawa shogunate as the government of Japan through a combination of democratic referendum and a vote in the National Diet. 

Japan in this story restores the Great Japanese Empire's combined armed forces, the Imperial Japanese Armed Forces, focusing specifically on the Imperial Japanese Armed Forces' ground warfare arm, the Imperial Japanese Army after its [the IJA's] restoration and begins a massive conscription campaign to rebuild the strength of both the post-WW2 Japanese united military forces without offensive capabilities but the right to self defence, the Japanese Self Defence Forces and the restored IJA. 

the extraordinary beings from a different dimension, with each having their own unique powers and abilities as well as the amount of spiritual energy they hold within their bodies, but all sharing the same ability to create their own armor or clothing created by their power which they can  change to whatever shape, color, style, or appearance they want known as an Astral Dress, as well as having an absolute shield that protects them known as an Angel, which can take many forms, from monsters to swords, all of which seem to display some special power  plus the ability to fly, who when they arrive to this world create an explosion akin to that of a nuclear missile hitting the earth and detonating known as a Spacequake from Date a Live, known as the Spirits from Date a Live, still exist like in canon Date a Live in this story with the Spacequakes the Spirits cause still being sold to the regular masses of the non-magical world as cosmic accidents and the elite, all female section of the JSDF consisting of mostly female magicians, witches and mages who mostly wear revealing strength and speed enhancing exoskeletons and use advanced plasma weaponry in combat known as the "Anti Spirit Team" from Date a Live that hunts the Spirits from Date a Live in order to protect the regular people of Japan from the Spirits  is still formed in this story.

Through a combination of diplomatic negotiations, covert military operations and international treaties, Japan manages to reclaim the entire Korean peninsula and Korea's Jeju Island, Russia's Sahalkin and Kuril Islands and Taiwan and the Pengu Islands without triggering intervention from the USA in Asia or the wrath of Russia and the collapsing PRC in this story. 

The industrial, military and economic and technological capabilities of the Korean peninsula along with Taiwan and the Pengu Islands are absorbed into Japan after it reclaims these territories in this story, further strengthening Japan and allowing Japan to develop nuclear ICBMs via reverse engineering of Korean nuclear technology in this story.

The Japanese also facilitate the restoration of the the Genghis Khan-descended Imperial House of Borjigin-ruled Federal absolute royal khanate of the Mongolian Autonomous Federation/Mengjiang in Inner Mongolia's Chahar and Suiyan provinces in this story. 

Covert intervention by Japanese intelligence and military forces in the eighteen provinces of the Han dynasty in mainland China to Han nationalists, Han monarchists and Han Democrats in China proper leads to the collapse of the PRC and the restoration of the stratocratic [military dominated/military governed] Beiyang Government-ruled presidental parliamentary republic of the first Republic of China as its [the first Republic of China's] short lived existence as the unitary parliamentary constitutional Royal imperial monarchy of the short lived Empire of China founded and lead by Yuan Shikai, albeit with the Ming dynasty's reigning Imperial family, the Jurchen-Manchurian/Han Chinese Imperial House of Zhu as the reigning Imperial family of this restored Empire of China instead of Yuan Shikai's descendants in this story.

academically talented but also very nerdy about Quirks and dreaming to be a hero despite being legally and suposedly Quirkless, but in reality having the powerful Quirk, "Guilty Crown", which allows the user to extract the "hearts" of others in physical form to use as a weapon and also to take, give, multiply and strengthen other quirks, Midoriya Izuku and [Shidō in this story] having Izuku's intellectual and [Izuku's] academic gifts along with Izuku's true Quirk of "Guilty Crown" but not Izuku's naivety and obsession with becoming a Hero and [Shidō in this story] having his [Izuku's]

buxom, kind and caring former top corporate executive turned loving housewife after her marriage to Hiashi, Midoriya Inko nee Shimura from My Hero Academia, [Shidō in this story having both Hiashi and Inko] as his [Shidō's in this story's] true self's [Rentarō's in this story's] birth parents [Inko and Hiashi] although the Itsukas in this story obviously don't know this [Inko and Hiashi being Rentarō's birth parents in this story] when they [the Itsukas in this story] adopt him [Rentarō in this story] [Shidō] finds himself [Shidō] in trouble in the law when Nana's apprentice who later became Japan's #1 Hero under his Hero alias All Might, the half American, blonde haired, blue eyed, tall, slender and lean, sarcastic and somewhat lazy but caring and determined bum with a Quirk that Nana gave him before her death, the Quirk that can be passed or rather copied from user to user which Hiashi's now long deceased younger brother, Yoichi originally had which stockpiles power and also

Hero Academia in his [Toshinori's] All Might persona trying to have Shidō in this story arrested for [Shidō' in this story] attempting to [Shidō in this story] resuce the Itsukas' biological daughter and thus his adoptive little sister in both canon Date a Live and this story, the red-haired, red-eyed, short, slender and petite but also secretly curvy and buxom, delicate, soft and shy and dependent on Shidō but having a charismatic, domeering side as well young Japanese noble heiress who is also one of the Spirits from Date a Live, being a flame based Spirit, Itsuka Kotori from Date a Live, who [Kotori] is [Kotori] also one of the Cursed Children in this story, [Kotori] having the agility, leaping skill and speed of both a rabbit and a fox due to her [Kotori] being infected with the Gastrea virus in this story and [Kotori] being Shidō's Initator under the name Aihara Enju [Black Bullet] when he [Shidō] was an Initator under his [Shidō's] real name [Rentarō] in this story, even though Shidō in this story has no idea that she [Kotori] is a Spirit or that Spirits even exist, and Kotori's classmates and schoolmates have no idea that she [Kotori] is a Spirit or a Cursed Child in this story, [Shidō' in this story rescuing Kotori] from a Spacequake, when she [Kotori] was [Kotori] visiting the former child solider and assasin Cursed Child with the sight of an owl using a sniper rifle and advanced drones in combat turned Initator, the blonde haired, blue eyed, short slender and petite, lively and hyperactive but naive young American girl Tina Sprout from Black Bullet,  [Shidō rescuing Kotori from the Spacequake just before she reaced Tina's residence] only to [Shidō with Kotori] stumble upon members of the Anti Spirit Team in a three way war with both another Spirit, who turned out to be the one behind the Spacequake and the Japanese branch of the Quirk users licensed to use their Quirks to protect civilians from Villains, natural disasters, and/or any other kind of harm, with three basic duties: rescue, evacuation, and battle known as Heroes from My Hero Academia, more specifically the Japanese section of those Heroes who take their job as a profession and are subsequently referred to as Pro Heroes from My Hero Academia which Toshinori as All Might belongs to, as the Pro Heroes refuse to believe the Anti Spirit Team actually exists and the Anti Spirit Team will stop at nothing to capture the Spirit, while the confused Spirit fights off both the Pro Heroes and the Anti Spirit Team. Shidō manages to sneak near the Spirit, who [the Spirit that causes the Spacequake] turns out to be the black-haired, black-eyed, tall, slender and buxom, refined, calm and ladylike, academically gifted and intelligent with a Quirk that allows her to create things from her skin fat, Japanese noble heiress and Pro Heroine in traininf Yaoyorozu Momo from My Hero Academia, who [Momo] seems to be [Momo] confused, scared and [Momo] embarrassed due to the revealing nature of her [Momo's] Astral Dress and the fact the Pro Heroes are after her [Momo]. 

Shidō revealed his presence to Momo and [Shidō] managed to [Shidō] convince her [Momo] to escape with both him and Kotori during the fight between the Anti Spirit Team and the Pro Heroes.

But the Pro Heroes later tracked down Shidō and are trying to have him arrested, while Kotori blocks them [the Pro Heroes] from arresting him [Shidō] and Momo is hiding somewhere in the Itsuka family mansion.

The excerpt starts with All Might accusing Shidō of wanting to carry on the Midoriya legacy of villainy and criminal ruling, which confuses the other Pro Heroes, to which Shidō is [Shidō] confused as he [Shidō] has always thought of himself [Rentarō/Shidō] as an Itsuka and [Shidō] has no idea he [Shidō] is even a Midoriya by birth as the Pro Heroes try to have Shidō arrested with Kotori blocking them [Kotori] from [the Pro Heroes] doing this [arresting Shidō]. 

Shidō retaliated to All Might's accusation by [Shidō] stating that if he [Shidō] was truly the son [Rentarō] of a villian [Hiashi as All for One], then why is he [Shidō] a decent, law abiding citizen [Shidō] and how come this villian [All for One] hasn't made the news as Kotori blocks All Might from coming closer.

The standoff is interrupted by Tina, who [Tina] had [Tina] made her [Tina's] way to the Itsuka family mansion and the current heiress of the Japanese noble family, ex-samurai clan and martial arts masters of the Tendō [Black Bullet/Ranma 1/2], the beautiful, fair-skinned, violet-eyed, dark brown-green haired, tall, slender and buxom, lively, serious and mischievous but also sadistic, malicious and very cruel Japanese noble heiress and swordsman in training who is also Tina's Promoter, Tendō Kisara from Black Bullet, who [Kisara] is [Kisara] also the oldest biological child of the Itsukas and Kotori's biological older sister, but also the older of  
Shidō's younger sisters along with also being a Tendō in addition to having a Sound manipulating Quirk in this fanfic, who [Kisara] had [Kisara] been secretly eying the conversation with interest before [Kisara] making her [Kisara's] move. 

Kisara then bluntly tells All Might that if the Pro Heroes are interested in [the Pro Heroes] hunting down a legend [All for One in the public mind] they [the Pro Heroes] can go ahead, but they [the Pro Heroes] shouldn't involve the Itsuka sisters' [Kisara's and Kotori's] shared adoptive older brother [Shidō] in this. 

Kisara also mentions that she [Kisara] knows about Kotori and Tina both [Kotori and Tina] comforting Shidō at night when Kisara was Tina's Promotor and Kotori as Enju was Shidō's as his true self Rentarō's Initiator during the war against the Gastrea when he [Shidō] slept, implying that she [Kisara] doesn't have a problem with the younger girls [Tina and Kotori] snuggling beside Shidō at night and [Tina and Kotori] also being [Tina and Kotori] among Shidō's wives later on, but that Kotori mustn't forget that she [Kotori] isn't Shidō's only fiancee because Kisara is also Shidō's fiancee as well, as Kisara captures Shidō's lips in a passionate kiss, causing the Pro Heroes and the Anti Spirit Team to both leave the Itsuka family mansion out of embarassment.
