[I only know the surface level of Touhou and never dive deeply, so yeah some of it are my interpretations]
Kusa can be seen jumping from puddle to puddle and making her clothes wet but it immediately dries and become new again
*splash* *splash* *splash*
Then suddenly the entire sky becomes filled with red smoke
Kusa: ehh? Is this blood?
Kusa: no, It's just coloured mist
Marisa: Kusa!!!
A voice in the forest can be heard
Kusa: Marisa?
Marisa: found you!
Marisa grabs Kusa and puts her into her lap
Marisa: ehh? Why did your flower accessory lose a petal again
Kusa: did it? I never noticed it
Marisa: ...
Marisa: you trust me right...
Kusa: despite you are being strong-headed, Yes...
Kusa: (I should dispel her worry)
Kusa: don't worry... I could solve this issue, so don't need to worry about it
Marisa: Mhm... promise me you won't disappear one day
Kusa: what childishness, yes I won't
Marisa smiles
Marisa: Don't take your word back!
Marisa speeds up towards the source of the mist
On their way, they bumped into Reimu
Reimu: Oh! Marisa and Kusa
Marisa: Reimu!
Kusa: Hello Reimu
Marisa: want to bet who will be the first one to stop the disaster?
Reimu: Bring it on
They continue their way when black bullets stop them
A girl appears floating and T posing
Kusa: ahh... it's Rumia
Rumia: Kusa! Nice to meet you but can you move away for a little bit because I want to challenge one of these two
Kusa: weird request but okay...
Marisa: wait you know this Yokai?
Kusa: Yes she is one of my friends to play with when I'm bored
Marisa: I see...
Reimu: Rumia is it?, then I will accept your challenge
Marisa: Good call Reimu, now Kusa let's move forward
Reimu: ehh?!
Marisa: bye Reimu!
Kusa: have fun Rumia
Rumia: Yes! Bye-bye
The two standoffs make an intense showdown
--------------------------------------------------------------
The two are currently at a stable speed with Kusa onboard every enemy they face is an instant knock out
Daiyousei appear in front of them and attacks them
Kusa: she likes to attack me without any reason
Daiyousei: you always bully Cirno!
Kusa: it's called duelling not bullying!
Vines appear in the water and grabs Daiyousei
Daiyousei: ehh?
The Vines throws Daiyousei away
Daiyousei: AAAAAHHHH...!!!!!
Marisa: you are quite cruel just you know
Kusa: they said something to me that will not be left in my mind
Marisa: What are those words?
Kusa: I won't say it cause it is incredibly hurtful
°It's a fake grass°
Marisa: there, there
Marisa suddenly rubs Kusa's Head
Kusa: (it's nice)
Kusa is having a blissful moment and Marisa is enjoying it too
When a voice can be heard
Cirno: Fight Me Human cause I the strong- AAAAAAAaaaaaaahhh!!!!
A light Beam hits the fairy and blasts her off on the horizon
Marisa ignores the scream and continues to rub Kusa
--------
In the land, there is a girl with a Green dress running
Marisa: Oi! Why are you running?!!
Kusa: Let's follow her
Marisa: okay
Meiling: tsk...
The girl shoots energy balls but it's easily evaded by Marisa
Marisa shoots some stars and the girl Evades it and she returns the shot when she can
Vast enemies Appear blocking Marisa's way
The girl that is running gets away from her
Marisa: tsk...
The enemies got wiped out instantly with Green lasers coming out from the ground
Marisa: Nice work Kusa
Marisa's broom emits light and their speed become faster
They have caught up with the girl and now she is posing in front of the Gate like a martial arts master
Meiling: you shall not pass
Kusa: this is the first time you've done your duty from what I see
Meiling: because it is the first time doesn't mean I will not take it seriously
Meiling: That's why prepare to lose-
When red blur can be seen accurately hitting her stomach making her blast towards the gate and destroyed it
Reimu: it hurts...
A shrine maiden can be seen in the top of the unconscious guard
Marisa: ehh...?! Reimu!
The shrine maiden dust herself then points towards the magician
Reimu: I don't want to lose especially towards you!
And she started to go-ahead
Marisa: I think we should go too
Kusa gives a silent prayer to the unconscious guard
Kusa: okay
They caught up to the shrine maiden and continues towards the mansion
The shrine maiden goes left while the magician goes right
Their journey seems smooth but suddenly
they got intercepted by flying books and magic
But because of Kusa, the magic books are disappearing the moment they arrived
A red hair devil appear and decided to stop them but a barrage of magic missiles from Marisa knock her out
Because of the development, the master of the library has appeared
Patchouli: Bring my books back!
A sleep-deprived purple-haired girl has stopped them
Marisa: like I said-
Marisa looks at Kusa
Marisa: If you defeat me I'll bring them back
Patchouli: hooh... it seems you've changed quite a lot, is it because of the tiny girl in your lap?
Marisa: who knows?
Marisa: Kusa let me fight her just don't do anything
Kusa: okay...
Patchouli: it seems you get full of yourself... let me cure that for you
They started exchanging bullets without letting a single one hit them
Patchouli Summons her books to shoot lasers and Marisa imitates her and shoots laser too
Marisa starts to shoot some star shape bullets
The Patchouli started shooting silver bullets towards the magician
Marisa answered it with her magic
shooting red, blue, and small green stars towards Patchouli
Patchouli dodges them and started readying her spell
She shoots big red orbs and some fireballs they scattered around
Kusa: does she not care about letting her library become burnt?
Marisa: just keep silent I want to see her reaction
Kusa: I see...
Marisa dodges while trying to hit Patchouli with her ordinary bullets
Marisa shoots a very fast bullet but Patchouli has a barrier protecting her
Marisa smiles
Marisa: Koigokoro "Double Supaaku"
▪︎Loving Heart: Double spark▪︎
Patchouli: wait! we can talk about this
Marisa shoots a very wide laser that swallows the whole library with intense light
The light dissipates leaving a giant hole in the wall
Kusa: though, what a terrible "loving heart". It's an annihilating love.
Marisa: Hehehe...
Kusa: *sigh* let's continue
Marisa: of course
The two continues their journey meanwhile Sakuya and Reimu heard the commotion
Reimu: what can I say... Sorry
Sakuya: it's fine it isn't the first time I've dealt with it
They continued their battle as nothing happened
Marisa: did we choose the wrong path?
Kusa: probably but we are going to meet someone
A blonde little girl that has Christmas wings has appeared
Flandre: Kusa! Nice to meet you again
Kusa: Flan-chan, yes Nice meeting you after yesterday
Marisa: you know her Kusa?
Kusa: she is one of my playmates
Flandre: Kusa who is this girl?
Kusa: She is Marisa
Flandre: Ahh! The one that you've always been talking about
Flandre: I heard that you are super strong so please accept my challenge
Marisa: ehh... Well I could, Kusa could you move away somewhere safe because I sense this girl isn't going to be easy
Kusa: of course
Kusa jumps down and a leaf catches her and moves her towards the wall
The two started to fight
Flandre started to shoot red bullets and Marisa shoots red stars Marisa is flying around while Flandre is trying to catch up with her
Flandre Uses the Taboo "CranBerry Trap" to make Marisa stay at the centre
Marisa counters it by using the brute force of Destroying the Bullets with her giant bullet
Flandre sees that Marisa destroyed her spell so she took out her metal wand and shoots red lasers that leaves red bullets
Marisa: I want that!
Kusa: you can't!
Marisa looks disappointed with those words and started to evade the onslaught of Flandre
Marisa shoots a blue laser towards Flandre but Flandre dissapears and four of them appears
They shoot different kind of bullets making Marisa sweat and tries to defeat them one by one
Flandre saw this and release a row of green bullets making Marisa stuck in a cage-like array she shoots a yellow big bullet
Marisa shoots her signature master spark destroying Everything
Flandre shoots brown and blue clumps of bullet and Marisa shoot them with her Giant bullet
Flandre emits a shadow that lessens the visibility of the Area but occasionally different colour bullets can be seen
The mist dissapears revealing Flandre getting hit by Marisa
She fires giant blue bullets that follow up small blue ones
Marisa frantically dodges and many of them just graze her
Flandre release two spinning lasers and she shoots curtains of red bullet towards Marisa
Meanwhile, Kusa is trying to mend every damaged they made so the Mansion will not collapse
Marisa dodges the bullets and releases some homing bullets towards Flandre
Flandre sees this and she tries to outmanoeuvre it
Marisa shoots a well time laser towards Flandre's path making her stop and got hit
Flandre dissapears and bullets appear coloured red, blue, and green making a rectangle shape getting smaller Marisa avoided them while having a lot of grazes appearing in her clothes
Kusa: (it's kinda erotic in someway)
Flandre appears to look frustrated and she uses her last world
Making thousand of bullets appear in the surroundings
Kusa: *sigh*
The walls are covered by thick greenery preventing the harm of the battle to damage the building
Marisa sees this and tries to avoid the Bullets but she got hit by some
She grabs the mini hakkero and started charging it
Marisa: Mahou "Fainaru Spaaku"
▪︎Magicannon "Final Spark▪︎
A very powerful and wide laser coming out from the Hakkero hitting Flandre square on
The plants bear the brunt of the laser but they didn't get burnt or destroyed easily
The Hakkero stops and Marisa is smiling
Marisa: Ha~ it's very refreshing
Kusa catches Flandre who is falling
Kusa: I didn't think you are going to use a planetary Destruction laser or something
Marisa: I mean she is super strong so I can't help it to give my admiration towards her
Marisa: you said, you and she are playmates
Kusa: yeah
Marisa: then did you mock battle?
Kusa: Of course (because of her I know that I'm unkillable because I don't have an eye in my body but my magic has tons of eyes that she got dizzy looking at it)
Marisa: heh... did you just use your solar beam to defeat her?
Kusa: at first, yeah but she wants to fight me fairly so we fight fair
Marisa: Did you lose against her?
Kusa: I never did... (mainly my plants protecting me 360 degrees and my sun spells are instant K.O that it isn't fair)
Marisa: one day we will spar
Kusa: okay...
Flandre started to wake up
Flandre: Kusa?
Kusa: Good evening Flan
Flandre looks at Marisa
Flandre: I lost...
Flandre: but I will make sure I will win next time!!!
Marisa: (Ehh?!! There's next time?!!!)
Marisa's face is twitching
Kusa is having fun with Marisa's expression
Kusa: yeah Flan, I'll make sure to drag her if you are ready to fight her
Flandre: Thank you Kusa nee-chan!
Flandre hugs Kusa like a little doll
Kusa: you should call your real sister like that and cheer her up because her plan failed
Flandre: I will!
▪︎Kusa managed to make the sisters have a reconciliation because Remilia's goal is to conquer Gensokyo to make people not hate Flandre and she can protect Flandre, while Flandre doesn't want to become a nuisance to her big sister so she stayed at the mansion for a long time but because of miscommunication they drifted apart▪︎
▪ a Tsundere Sis-con▪︎
They meet up with everyone and Reimu is Grinning happily because she won at the bet
Remelia hugs Flandre while crying
Sakuya started to pick up her knives
Patchouli is staring begrudgingly at Marisa
Meiling is sleeping while standing
Kusa is on Marisa's head enjoying the atmosphere and Marisa is being bitter at Reimu's Smugness
