This ship was created when the episode Karai's vendetta aired on April 27 2013. Listen I created this ship when the episode came out because I saw a connection between Karai and April. Here is what I said the day after I wrote down there ship name. (Which is Karpril).
I have noticed that Karai and April have similar personalities. They are strong fighters, they both lost there mother's at a young age, they are both being raised by there father's, they are both a little rebellious at times, they are both compassionate and kind, they are strong in there own ways.
This is another reason why I created the ship is because in Karais Vendetta I noticed a few thing's that caught my eye and I made a list in 2013 and this is what the list said.
1) I noticed that Karai and April have a lot in common
2) they both care about the people that they love
3) Karai had her hand resting on her face and she was staring at April so deeply
4) also I noticed that Karai was smiling at April
5) April also stared at Karai and smiled at her
6) it seemed to me when April and Karai talked April was a little shy
7) Karai showed sympathy for April
8) It seemed like Karai and April really enjoyed talking with each other and sharing there similar situations
9) Karai called April princess
10) Karai didn't hurt or attack April first April kicked Karai.
I was afraid to admit I created this ship because I thought people would reject it and be so rude. I held onto this information about me creating this ship until now because I think it's safe to share this information with every one.
