At the turtle secret lair four ninjas are doing their thing as usual leonardo is meditating, rapheal is punching & kicking a dummy, donatello is working on the computers and michelangelo is skateboarding through the sewer line hall when he notice a book, an old book about the cardinal weapons he see strange emblem mikey decide to pick it up & show it to his brothers after mikey return to the lair he call out rest of turtles

Mikey: hey guys I found something!

the three turtles look & saw mikey was holding some book then donnie ask

Donnie: what is it mikey?

Mikey: I found an old book

Leo: a book?

Donnie: what kind of book mikey?

Mikey: well it's say the history of the four cardinal weapons here take a look

mikey give the book to donnie; the trio look at it & see weird symbol then ralph ask

Raph: well what you think it is donnie?

Donnie: I don't know there no author name not even an address or anything

Leo: well do you guys think we should do?

Donnie: well I think we should read it see anything interesting

Mikey: well I read a ton of comics books but I guess reading a book wouldn't hurt

Raph: yeah we got nothing to do today besides the city had been quiet since all of the baddies are put away so in my mind I say let read it

Leo: alright since I'm the leader I'll read it let go the living room so we can see it

the turtles go the living room there they all sit down then leo open the book & start reading it

Leo: the four cardinal weapon; in order to save the world from the wave of apocalyptic catastrophe four heroes will be summon from another world huh

Mikey: another world that so cool!

Donnie: yeah remember ultimate drakko set us different time & space?

Mikey: or the time we met our duplicate?

Raph: yeah the four of us willing save our world

Leo: and we manage defeat our enemies so let see what else does said hmm got it each hero wield a distinctive weapon; a sword, a spear, a bow & a shield

Mikey: a shield? sound cool guess it has some good defense power

Raph: yeah the shield ain't that bad for someone need for block a attack

Donnie: plus it great to protect the people & rush through the battle

Leo: yup but there more it said the sword hero has great strength but unable accept reality, the bow fight for justice unfortunately being arrogant, the spear hero is undying loyalty also foolish only the shield hero is the true hero he protected the people, fought some enemy & anyone who always believe in him

Mikey: woah I guess some hero had bad hair day

Donnie: you said it mikey my bet is the shield hero because he seemed like a good person

Raph: yeah he always be a good guy what else does it's said leo?

Leo: well the country know as melromarc is a human population they put the poor Demi humans into slavery because both melromac & silvelt a country of Demi humans had a civil war between each other most of civilians has lost their lives it put stop their assault if not for the shield hero always kind to the Demi humans never abandoned them

Raph: man talking about a civil war sound rough

Donnie: I can't believe they were fighting each other

Mikey: well glad the shield hero stop it keep reading leo

Leo: in melromac there is a corrupt king & princess the king hate the shield hero thinking he is devil & the first princess is a pathological liar using alias name as adventurer making the heroes against each other for her entertaining making her sister next in line of the throne

Mikey: ok that bad the king is a jerk & the first princess is horrible woman

Raph: well I wouldn't be able trust them if they up to no good

Donnie: my guess probably the queen know everything about her family, more powerful than the king & put her second daughter in line the throne

Leo: seems like melromac must be horrible place still they can't fight against the wave without the heroes help, who knows more lives would able lost

Raph: bro I feel y'ah but we don't want the same mistakes after everything has happened

Leo: I know raph now let see ok the queen went to travel to meet with other country leaders to bring peace, become allies & agreed to summon one hero from each country to rally against the wave of catastrophe

Mikey: ok that more like it they could use more help

Donnie: the queen must good person know the right thing

Raph: I guess not all aren't bad she trying to protect her people

Leo: well guys I agree after what happened to another world everything has change & the heroes are main protagonists the sword hero, the spear hero, the bow hero, & the shield hero

as leo turn the next page he see a blank page flipping another still blank then another also blank leo said

Leo: hey guys! the rest is blank!

Raph: wait what!? what do you mean is blank!?

Leo: let us explain our story to help you & young girl understand

both naofumi & raphtalia nodded they began their origin how they came to be including their master next they fought their worst enemy like the shredder, the foot clan, the purple dragon gang, the triceratons & more then they met some humans who are in trouble or getting into also team of real superheroes and went different & space to meet their duplicates from another dimension after that naofumi & raphtalia were quite shock but understand then naofumi spoke up

naofumi: wow that quite some story

raphtalia: amazing! I never knew there another world existed! & you're brothers!

Mikey: yeah it get pretty awesome once you get in our dimensions

naofumi: wait how did you all get here?

Leo: well one of us found a book that said the cardinal weapons about the heroes & the country melromac but as I read is starting to glow then it transports us to here next we fought some enemies who aren't that great then we were walking until we found a village & a mine now you know the rest

naofumi: wait you said the four of you got transported by book? that what happened to me!

Mikey: really you got transported too?!

naofumi: yeah the world I'm from is Japan I was walking toward the library to pick a light novel when a book fell on my head then pick up I read like you said next it's starting glow I got transport to another world it's turn out I'm one of cardinal hero the shield hero

Mikey: wait you're the shield hero?

naofumi: y-yeah

Mikey: that so awesome!!!

naofumi: wait really?

Raph: yeah having a shield ain't that bad someone need to protect

naofumi: really? but the other heroes said in their world video game the shield class is weak that means I'm the weakest

Donnie: that's not true just because the shield in their game isn't great doesn't mean the same thing in real life plus you be great using the legendary shield

Leo: and with proper training you become the greatest hero the world ever know don't let other people or heroes get to you they don't understand how this work just keep working hard then you do great

naofumi is surprise for the turtles just say usually people say the shield hero is weakest but these turtles say really cheered him up bit then he continue his story

naofumi: thanks really means a lot but there more as me & the other heroes summon at melromac castle to meet the king who told us about the wave of catastrophe the next day the adventurer except one didn't join me her name is myne sophia then one day I was taken the royal knights to the throne room claiming I rape my party member & proven guilty all because she betrayed & framed me, stole my equipment & giving and join motoyasu kitamura the spear hero I try tell them I really didn't do it but no one believe me I been outcast by the king & set out to find anyone who willing join me

the turtles & raphtalia widen their eyes & shock they couldn't believe it naofumi is framed by adventurer then he continue

naofumi: then I met the slave trader for giving me a party member that where I met raphtalia the girl who with me she was sick & has illness so I buy her but remove her slave crest because he said once a slave has the slave crest they won't betrayed you & listen what they said but it's hurting her so I pay extra to slave merchant so he can remove it

raphtalia: it's true master naofumi be taking care of me, giving me food & medicine then I had nightmares about the monster who kill my parents he cuddle me so I would calm down

naofumi: then I been training her so she can for me next we were heading the village so we can buy something I ask the guy who from the village anyway to raise some money he told me about crystal but It was guarding by that the hound dog during the first wave so we heading to the mines, found some crystal then raphtalia got scare by that monster because she said it was the same thing that kill her parents so we got attack then you guys show up to save me & raphtalia

the turtles still shock after what happened but they glad he treating her with his kindness then leo ask

Leo: wait you & other heroes were summoned at the castle?

naofumi: yeah why?

Raph: oh boy that not good that's not good all

Mikey: that was not cool

Donnie: the king isn't supposed to summon all four heroes

naofumi: wait what?, what do you mean?

Leo: well the book said the queen is traveling to meet other country leaders to bring peace next put an alliance then summon one hero to each country so they rally together against the wave

naofumi: what?! then that would means...

Donnie: the king summon the cardinal heroes on his own

Leo: also that female myne sophia probably the first princess because the book said she use alias name & a liar put the second princess in line of the throne then the king hate the shield hero because he still believe he is the devil

naofumi couldn't believe now he understand why the king was treating him this way because he believes myne sophia who actually a princess & her daughter & hate him for thinking he is the devil

naofumi: I can't believe it the book from my world said the princess is a liar but not the rest I should've known I just didn't see it

Leo: hey don't beat yourself up you didn't know I understand how you feel

Raph: he's right that corrupt king & fist princess up to no good
