If you downloaded the pack, you'd see a generated male character looking like Makato from Persona 3.
I actually did not try to call any particular character and used my methods for Niji 5 to generate whatever I could. In a really funny way, MidJourney's Niji 6 has a huge bias for Kirito from Sword Art Online, Byleth and Shez from Fire Emblem, Naofumi from the Rising of The Shield Hero. Niji 6 relies heavily on your knowledge of what you're trying to generate.
All of my prompts are keyword-based, or.... uhhh... Lego-like. Niji 6 is really good at swapping in and out of character-based keywords. You can put in and pull out and the generations will come out different all the time.
My next pack's theme is going to be on the LitRPG Genre, I am glad you're enjoying thos pack though!
If asked, I am willing to share how my prompting is like. Although, I have been too busy to write up a web page for it.
