The ultimate life form of Gensokyo (touhou harem x oc) (Completed)

Prologue: the ultimate hero emerges in Gensokyo.

After defeating Ganondorf for the umpteenth time Toad was about to head back home when suddenly a different portal appears and he noticed an arm reaching for him. Curious he took a closer look but was grabbed instead. When he opened his eyes, he noticed that he wasn't in New York anymore. So he decided to look around but was grabbed by the shoulder by the same arm that he saw through the portal and was greeted by a tall busty blonde.

????: hello cutie.
Toad: uh hi? Who are you?
Yukari: I'm Yukari Yakumo. I'm the one who brought you here.
Toad: uh ok why?
Yukari: I noticed you were bored with the life you currently have so I decided to bring you here to spice it up .
Toad: oh. Do you know who I am?
Yukari: of course I do! You're Toad Skywalker. The ultimate life form. Also known as the hero of time and space.
Toad: true. But in the past I was known as the angel of death. And the angel of silence. A cold hearted assassin.
Yukari: oh really? Why is that?
Toad: y'see back in middle school I caught my girlfriend cheating on me with the guy who bullied me. I was so distraught that I chained my emotions shut. Causing me to be silent. Overtime I was scouted by an assassination guild and I joined them. As time went on I became highly skilled at killing my victims without being seen. I returned to the school a year and a half later, when I saw my ex girlfriend she ran to my chest crying. I asked her why and she said that the bully was only using her just so he can attract the schools head cheerleader. And she promised me that she would never cheat on me again. Which caused me to release the chains that sealed my emotions. And I went back to normal. When we entered highschool she decided to move in with me and she became overbearing and overprotective. Eventually I had to break up with her for being too clingy. So I moved out of my old house. And here I am now.
Yukari: wow. That's just sad. I feel so sorry for you. But don't worry I'll heal your broken heart. I also know that you're the ghost rider. Otherwise known as the spirit of vengeance.
????: hey Yukari! I saw a portal around here and I thought you were responsible.
Yukari: of course it was Reimu. Because I wanted to bring a new face to Gensokyo.
Reimu: who are you supposed to be?
Toad: if you mess with me then I'll be your worst nightmare.
Reimu: y'know what? Now that I get a good look at you you're actually really cute.
Toad: that's not the reaction I was expecting. Anyway I got no home so I think that I'm gonna roam around for a bit and see if I can find a place to live. Smell ya later!
Yukari: my he's quite the charmer.
Reimu: am I missing something here?

Soon after he was walking through a forest and he saw a little girl.

????: what are doing here mister?
Toad: don't mind me. I'm just passing through.
????: oh. So can I eat you?
Toad: do it and I'll slit your throat.
????: oh c'mon! Let me eat you!
Toad: don't make me hang you by your intestines!
????: who do you think you are anyway?!
Toad: your worst nightmare. So you like eating people? Then how do you like it if I devour your soul!
????:h-how are you gonna do that mister?
Toad: with this sword! The demon sword SOUL EDGE!!!!
????:*screams* GET AWAY FROM ME!!!!!
Toad: tch. Pathetic.

Toad made it out of the forest as expected. He came across a mysterious mansion and decided to approach it.

Toad: huh. This place looks pretty nice. It's a lot better than my dad's mansion that's for damn sure.

When he reached the gate he saw a woman sleeping so he just walked right passed her but was stopped by a silver haired girl in a maid uniform.

????: who are you and what are you doing here?!
Toad: I saw the gate was open and the gatekeeper was asleep so I just walked right in.
????:dammit Meiling! I'm so gonna tear her a new one when she wakes up!
Toad: hey you can't blame her! You're the one who gave her the crappy job!
????: you dare talk to me that way?! I, Sakuya Izayoi shall be your opponent!
Toad: bring it on hot stuff! I don't enjoy hurting women! It goes against my policy!
Sakuya: good to know. That makes this a lot easier for me to kill you!
Toad: I'd rather go out in a blaze of glory but I guess this works too.
Sakuya: what?! You can't be serious?! You would die in the hands of a woman?!
Toad: yeah pretty much.
Sakuya: how foolish! How dare you mock me!
Toad: I did no such thing. Those were your words not mine!
Sakuya: ENOUGH!!! I WILL NOT HAVE YOU INSULT ME ANY LONGER!!!!
Toad: alright I guess we have to do this. MANKYEKO SHARINGAN!!!!
Sakuya: WHAT?!!!
Toad: TSUKUYOMI!!!!
Sakuya: w-why can't I move?!
Toad: you're caught in my genjutsu.
Sakuya: wh-who are you?!
Toad: I am an avenger. Just kidding. I'm Toad Skywalker. Nice to meet you Sakuya!
Sakuya: I can move again. Now answer my question. What are doing here?
Toad: well some busty blonde chick dragged me here through a portal she opened so now I'm stuck here.
Sakuya: so it was Yukari who brought you here? Interesting. Do you have a anywhere to live?
Toad: nope. Not since I left my old life behind.
Sakuya: then perhaps I can ask my mistress if you can live here.
Toad: that would be greatly appreciated. Thanks.

When they entered the mansion, they met with mansions owner.

????: so let me get this straight. You came here through a portal that Yukari opened and now you don't have a place to live?
Toad: that's pretty much about the gist of it, yeah.
????: very well then. You will be living in this mansion from now on.
Toad: cool thanks shorty!
Sakuya: you will address her as mistress Remilia Toad.
Toad: now that I get a good look at you I'm guessing you're a vampire.
Remilia: clever boy. Your guess is correct.
Toad: and Sakuya. I can tell you have a girl boner for her huh?
Sakuya: y-you can't prove that!
Toad: dude I just saw your nose bleeding .
Sakuya: she-shut up BAKA!
Toad: yup. She's a total tsundere.
Remilia: oh yes before I forget Toad be sure to keep away from my sister Flandre.
Toad: why would I do that?
Remilia: because she can't control her power.
Toad: that sucks. must be hard.
Remilia: I agree. Which is why we have her sealed within the mansion.
Toad: but if you do that then she won't get any exercise! Her bones will become stiff and her movements will become sluggish!
Sakuya: how do you know that?
Toad: experienced as a shut in otaku. Even I need to get outside often. Exercising is important.
Remilia: *laughs*you have indeed piqued my interest Toad.
Sakuya: *blushes* (what is this feeling? I've never felt this way before. Is it because of him? It's true that he's handsome. But still.)
Toad: yeah I get that a lot. So where's my room gonna be?
Remilia: your room will be next to Sakuya's room.
Toad: alright cool. Lead da wae Sakuya.
Sakuya: why did you say it like that?
Toad: because I know da wae to ebola. *clicks tougne*
