Celipse

After Amihan, politician by day and otaku by night, died from a political assassination, she got transmigrated as the saintess in another world. But she always felt like a fraud. Why? If she was the chosen one, why did she feel so rotten inside? 

Also, wasn't she atheist?

However, her years of forced piety and suppressed desires ended in spectacular failure - her decapitation.

Three days later, she woke to the sight of a worshiper bowing low. “Welcome back, O Sun Who Burns The World,” they said.

'Wait. What? I'm not the Saintess? I was this all along?'

Furious at the wasted years of celibacy, moral dilemmas, and suffocating oaths, Serafine made a vow: no more pretending. No more rules. The world? Hers to ruin. The people? Playthings. 

But wait. It was harder than she thought because...

How in the name of the Goddess Aurelia was she supposed to have her debut when she was surrounded by a bunch of suspicious and crazy beautiful women who wants to hunt her down?!

This was no different from her previous world!

Serafine tilted her head. Now that was interesting. Somewhere in the hazy depths of her previous system tutorials which she had, admittedly, half-listened to, she vaguely recalled that most of her actions were now completely up to her, meaning she had some free reign over how she wanted to handle things.

A delighted grin spread across her face.

'Oh-ho, so this means my glorious future acts of debauchery and chaos will be handsomely rewarded?'

She nearly cackled in glee, but she held it in, settling for a suspicious little snicker under her breath.

Calix, walking beside her, took one look at her and shivered. "Why do I feel like you've just discovered something terrible?"

She ignored him, far too pleased with herself. "Open my stats," she commanded.
