Brave, impulsive, or loyal
"Tango... you have horns... and wings... and a tail... you... you're a demon...?"
"Impulse, please, let me explain!"
"You also have that mark on your forehead. And your horns are longer. You're the prince."
"Impulse, please,"
"You've killed hundreds of innocent people. You lied to us."
"Please don't tell Xisuma!"
"... why wouldn't I tell Xisuma that a demon has been among us this entire time? You could easily kill us all."
"I promise I won't hurt any of you!"
"I'm not lying to Xisuma. I know what you demons are like." Impulse turned around to go alert Xisuma before something hit him in the back of his head, and everything went dark.
Impulse woke up in some sort of prison cell, with chains around his wrists. Some unfamiliar demons walked down some steps, opening the cell and dragging Impulse along with them. He felt a tugging at his chest, and then once again his vision faded. Except this time, he didn't wake up.

Tango looked down at Impulse's limp body, an apologetic expression on his face. In his hand, he held a glowing orb of life - a soul. "I'm sorry Impulse," he said as Impulse's body rose, eyes lifeless. "I couldn't let you get in the way of a new life." The two would return to the village as if everything were normal. Xisuma would ask Impulse where they were, and Impulse would reply that they went on a walk. No one would notice that it wasn't Impulse speaking. (You got the bad ending...)

Kind, empathetic, or a coward
"Fine. Then what is it?"
"You'll really let me explain?"
"Yes. It better be good."
"I just wanted to be able to have a new life... I've really enjoyed my time with you, and I don't want to lose it..."
"So you aren't going to hurt us?"
"Never! In fact, I've been convincing my father to leave your town alone."
"Oh... I never realized... I always thought you demons were heartless..."
"Heh, maybe most... but not me!"
The two laughed, spending the night together. Tango explained his life as a demon, and how boring it got. Impulse was just glad to help and glad to not be worried about getting killed. Eventually, Tango started secretly providing money and resources for the village so they could break out of poverty. Now, the village is strong. Impulse and Tango got a nice house together, and so did most of their friends! Xisuma is the mayor of the village now, and there is no longer any poverty. Xisuma and his friends are now working on helping other villages in need, and the demons are still blind to the power that the village had gained. All this was because Impulse stayed by Tango's side the whole time. (You got the good ending!)

Lucky or a team player
"I-I..." Impulse stammered, frozen.
"What's going on here???" Zedaph said from the door. Impulse let out a sigh of relief. Tango looked at the two nervously. "I-I... I mean no harm!"
(The next part is based off of Zedaph's decision, but whatever happens, Zed will protect you. If you are to attempt to tell Xisuma, Tango will be unwilling to fight both of you at once, and will flee, getting an ending similar to the smart persona ending. If you are to accept him, you will get the good ending, except Zedaph will live with them and they might even get together!)

Smart
"... what do you want from me?"
"I just... I just want to have a new life with you guys, and I'm afraid Xisuma will kick me out for the safety of the village! All I ask is that you don't tell Xisuma... please..."
"Alright, fine."
"Really?!"
"Yes. Now, I'm going to sleep."
The next morning, everyone met up to discuss their plans for trading, as usual. That was when Impulse turned to his peers. "I have an announcement. And it's important."
"What's wrong?"
"I found out that 'Tango' has been a demon this whole time!"
Tango's eyes widened in shock. "Y-you said you wouldn't tell!!!"
Impulse stared at him coldly. "You lied to us. Did you really expect me not to lie to you? You're a threat to our village. I'm not going to betray them."
Tango's eyes met with Impulse's, betrayal evident in his eyes. He then turned around, revealing his demon features, and flew off. Life returned to normal, except the ever-lasting guilt. After all, Tango never got revenge on them.

Secret Ending - Outside Interference
Impulse didn't say anything. He just stood there, frozen. Through a portal, the Portalverse hermits watched. "It's Christmas. This won't do." PV Tango said. Waving PV Stress over, he whispered something in her ear. She nodded, gathering the snowballs. Back in the AU, Tango opened his mouth to say something until a snowball hit him in the head. Then another, and another. Looking up, snowballs were raining from the sky. An exhausted Xisuma exited his house to check out the commotion, before freezing at the sight of Tango. He was about to shout something in surprise, but instead got a mouthful of snow. Over the world, demons were getting pelted to death with snowballs. And then all the demons died except for Tango and the Ice Age began. Oh, and it was Christmas and their Christmas presents were not dying to the snowballs and having freedom. The end.
(The secret ending is so serious! I know!)
