This AU is destroyed/ended. The characters that only survived is Chara and Frisk. And yes, in this AU, Frisk and Chara are NOT gender less. If you know what is taijitu, then you'll know what this AU is about.

For those who don't, Taijitu means the Yin and Yang circle. Taijitu is an AU of balance. After the AU ended, Frisk and Chara are the only survivors. Frisk was Yang and Chara was Yin (Yin is Darkness, Yang is Light). Frisk and Chara has been battling each other for decades in their AU. Soon, both grew tired of their conflict and decided to make peace. As you can see in the soul, Chara has a small fraction of white while Frisk has a small fraction of black. They exchanged a small piece of their soul of Light/Darkness, allowing them to be in a peaceful situation.

For the reason they're not gender less in this AU, it's because Yin is feminine and Yang is male, in Chinese traditions. So, I decided to make Chara a female and Frisk a male. The bands/ribbon around their head shows their colour of past, meaning they're still the same Frisk and Chara but more wise now.

Both venture around AUs together in hoodies to hide their identity and maintain peace.

If they gave each other a small fraction of their soul, does it mean that they're related now? You may ask, well yes. I wanted them to be related in the first place considering they're both adopted children of the Dreemurs.

Welp, that's all for Taijitutale.
And I mean it. I think Yin and Yang (Chara and Frisk) might just top my Oc Blueberry!
Yin and Yang is now my assistant as for Blueberry, she will be as a daughter of mine. And Oc daughter. Since I am her creator after all 😏.
So, Yin and Yang will be very frequent in all books featured now hehe.

OH! Also, if you wish to feature them in you stories, go right ahead, just remember to credit their creator aka me. 😊
