is it wrong for a cyborg to fight in a dungeon? (danmachi harem x op male oc)

Journey to a new world.

Toad pov.

I'm Toad Skywalker and I'm a hardcore otaku. Recently my girlfriend cheated on me because I'm weak but I don't really care. I mean why should I care about her anyway? She made her choice and I made mine. Well on the bright side at least I didn't lose my mind and became the joker. But I digress. She means nothing to me now. I just got back from the game store because I just bought the game I've been wanting for a while.

Toad: yes! I finally got the game I've been wanting to get for a while! Goodbye cheating ex girlfriend, hello "Batman: vengeance "!
????: h-hey Toad. How you've been?
Toad: what do you want now Nozomi?
Nozomi: Toad I know I've messed up. But all I want now is to make things right! That guy means nothing to me! He only used me for my body! I can't live without you! Just give me another chance! I promise I'll never cheat on you again!
Toad: don't make promises you can't keep. Besides, being around you is making me lose my sanity. Any longer and I might become the joker.
Nozomi: then I'll be Harley Quinn.
Toad: and why would I want that?
Nozomi: because I love you!
Toad: *sighs* I'll think about it.

Just then a magic circle appeared and dragged them in and they ended up in a different world.

Toad: huh? Where are we?
Nozomi: Toad I'm scared.
????: who are you people?
Toad: I'm Toad Skywalker and this is my ex girlfriend Nozomi Toujou.
????: I am the goddess Hestia. As you can see I have no members for my familia.
Toad: sounds rough. Well I'd love to help but I have my own shit to deal with.
Nozomi: oh no you don't. If I have to suffer, you will suffer with me.
Toad: *under his breath* I hate my life.
Nozomi: I heard that!
Toad: you heard nothing devil woman!
Hestia: well at any rate, welcome to my familia.
