Mangaka Yuri Tarou, creator of Chie-sensei Can't See It, 
followed by Kaya-chan isn't scary comes a story of a misunderstood problem kindergartener Kaya, who is a fearless powerful psychic who protects people around her from dangerous monstrous spirits. 

While her classmates first fear her as they slowly stop their misinterpretation, the first to believe in Kaya is one of the teachers, Chie-sensei.

In addition to that, there's an omninous mystery to her family... and herself.

... In my opinion, this manga is underrated and has a lot of potential.
From the character of Kaya as a child, and the perspective of Chie-sensei learning of Kaya's life, to the terrifying mystery of Kaya's family and what's inside her. This manga stands out and deserves licensing for English translation.

Subsequently, and for a better chance, with an English Publisher who already does business with Shinchosha's Kurage Bunch.
Who are Comikey, Viz Media, Yen Press, Seven Seas Entertainment, One Peace Books, INKR Comics, Manga Plaza, 

I personally recommend Comikey for their economical keys payment system and chapter release.
They also have the most publishing manga with the original publisher, so they're more likely to license it.

Anyway. These are the best options to contact;
Email (support@comikey.com) or discord Comikey.
Submit a request to Viz's Manga Licensing Suggestion form. 
Contact or Email (yenpress@yenpress.com) Yen Press.
Contact or fill Seven Seas Entertainment's Reader Survey on the right of their website.
