Alright let's start with our little speedster's harem shall we?

Callie

Once Kaze saves her from Ocatvio, she'll think of Kaze as her hero as well as already being a big fan of him and fall madly in love with him. (Similar to how Amy fell madly in love with Sonic during the events of Sonic CD).

Marie

She'll be pretty interested in him due to his abilities and potential as an agent once she recruits him. She'll slowly fall in love with him due to his personality and how he is such a gentleman as she watches how strong he is.

Pearl

Pearl will judge him at first and be wary of him, but will slowly fall in love with him as he does good things and helps others, gaining her trust completely.

Marina

Marina will slowly fall in love with him as she gets to know our little speedster more, as well as him being a gentlemen and respecting women and him doing so much for her.

Agent 3(Elizabeth or Liz for short)

She wouldn't really trust Kaze since he's human and thinks he might be dangerous, as well as looking down on him thinking he's normal as well as "useless" (how wrong she will be) despite him helping out during Octo Expansion. However she will start to feel a little weird whenever she's around him and will later realize she's in love with him.

Agent 4(Emma)

She'll be paired up with Kaze during their mission on getting the Great Zapfish and Callie back. She'll grow a strong admiration for Kaze as she sees his skills up and personal. Slowly she'll fall in love with him.

Agent 8(Bridgett)

Now this sweet little cinnamon role is a small bean. Her mind is too innocent, so she won't understand things like love but will slowly start to feel weird around Kaze when she starts to hang out and getting to know him. She'll find out what love is later on with the help of the other girls.

Roxanne

She was one of Octavio's soldiers. She was under control due to the hypnoshades. She was caught up on fighting agent 4 and Kaze ended up knocking off her goggles after realizing she wasn't in control of her actions at all, releasing her from the mind control. After thanking Kaze, she starts to flirt with him and be a little clingy towards him. Agent 4, and the other girls will get quite jealous of this, Roxanne will become a pervert from time to time.

And lastly Ava

This orange tentacle haired inkling girl was getting harassed by some perverted inklings and would have been raped if it weren't for Kaze coming and curb stomping those perverts. Since then she's been madly obsessed with Kaze and became a Yandere for him.

And that's his harem. I'll probably add more but I'm not sure. Anyway I hope you guys enjoy this story, until next time. See ya
