Rhine

The fallen primordial angel and the primordial demoness, both are the personification of the deadly sin of sloth and harbor feelings of anger towards each other, due to the fact that they were created as opposites to each other, although they personify the same sin.

Who could have thought that a spark could ignite between them, not a spark of friendship or a soulmate, but love, but it’s hard to call it love, although everyone around knows about Rain and Dino’s feelings, it doesn’t stop them from remaining friends and bickering between each other because Dino dumps work on her, and she dumps it on Misery, and then Misery scolds Rain

But about 4-3 years passed, during this time a lot has happened, the appearance of a new prince of darkness and he became the meaning of life for Dino after the death of his lord Veldanava, he began to watch Rimuru and after the sacred great war of Tenma he became a resident of Tempest

When Rain was talking to Rimuru in secret from Guy and she noticed how Dino was carefreely lying on the floor with the ancient princess of darkness and the true dragon, she felt dependent on his permission to be lazy, but also something new, unpleasant. When she saw how Ramiris pressed herself against Dino to look at a picture in the manga, Rain's heart sank with anger and she restrained herself from yelling at Dino.

Soon another Walpurgis Night was scheduled, and they discussed what had happened since Rimuru's appearance. Rain watched Dino the whole time and again felt that unpleasant feeling when one could think that he had feelings for one of the other princes of darkness, but mostly Rain was winding herself up and in fact Dino was just a loyal friend to some princes of darkness.

After the end of Walpurgis, she went to Tempest and, having made a deal with Rimuru about the drawings, ran into Dino when she wanted to leave the house. * — Oh, I'm sorry..

• Rain said at first, not understanding who was in front of her, but then she blushed looking at Dino *. — Hey! What are you standing there for?! Let me pass!
• Rain shouted, looking like a little child and not like a demon who had been tenacious since the creation of the world, and now her face from her ears to her neck was all red from embarrassment.
