The second to the last chapter probably It doesn't show a lot of Klaus...

by the way, to answer all of your questions, Klaus is Nyaa. The human one in the manga. 3

This has been Kanami-chan!

An Angel in danger

Klaus said nothing as he looked at Misha coldly. He ignored her question and the terrified look at her face. He looked at Shia and then nodded. They both had cold expressions on their faces that sent a chill down Misha's spine. Klaus then took Misha by her hair and started dragging her.

Misha then squirmed, trying to move away. She then touched his hand causing him to pull his hand back. Her wings appeared from her back and she flew into the sky, tears falling off her eyes. How he reacted to her touch was proof enough... he has turned back into a demon. She shook her head and wiped the tears off gently. She flew back to the heavens and leaped into Sasha's arms. "Sasha, su! It's howwible! Really weally howwible!" Misha said. Her words mixed with the whimpers of her tears.

"What happened, dear?" Sasha said gently patting Misha's head. She then gave her a handkerchief to dry her tears with. Her face was filled with worry.

"Klaus, su. He-!" Misha said, burying her face deeper into Sasha's shirt. "He turned back into a demon, su!" She said looking up at Sasha with a pleading face. She was trying to tell Sasha to help her. She wanted Klaus back.

"I told you, dear. To not go too close to that demon. Don't worry, you're safe, I'll tell them to cancel your mission or assignment." Sasha said letting go of Misha. She smiled reassuringly at her.

Misha looked at Sasha with disbelief and then pushed her away. She ran and then flew back to earth, going to the tallest tower she seen. She then remembered that this was the first time her and Klaus had a real talk and this was also the place where her Kotarou first opened himself to her. "This place is full of memories... special memories... su." She sighed and smiled gently. Birds then flew around her.

"Birdies, SU!" She then looked at them and they looked at her back with a confused face. "Are yas wonderings why I'm crying, su?" She mumbled slowly.

"Its cause.su.." Misha began and took a deep breathe. "My friend, su. He hates me now." She said in a whimper. She didn't want to start crying while she was telling the story so she tried to smile. She pet the birds in the head as they chirped in response.

"It must be something I did, su." Misha hanged her head low looking down on the bottom. Her tears flowed from her eyes, slowly but silently. The birds turned their heads in confusion and pecked at her head. For Misha, it was like they were trying to give her confidence.

Her eyes glowed at them. "Thank yas! Thank yas! Thank yaaas!" She looked at them and carried them. "I knew from the beginning that Angel and Demon love is forbidden...su" Her face then turned hopeful. Her pink hair flowed in the wind and her face looked peaceful. "But... su" She continued breathing for air. "I can't help my beating heart, su!" Misha smiled gently. The birds then sang a gentle song for her.

"Thank yous. Su!" she said as she stood up. She then looked down from the top of the building to the very bottom. "I won't care what anyone says about him, su!" Misha smiled. "He's the best person ever, su! I want him to stay with me always, SU!" Misha then let go of the birds. "Thank yas, birdies! I'll see yas, later, su!" She flew happily into the sky and looked for Klaus on the ground.

"Have you completed it? Your mission, Klaus?" A dark figure appeared in front of the demon. His face and whole body was covered with a black cloth. Klaus bowed down to him and looked sternly at him.

"No, sir, I'm afraid I haven't." He says, forcing Shia to bow with him. He then looked at the ground with red eyes. "I promise..." he began, clenching his free hand. "I won't fail the next time I see her."

He walked away with satisfaction. He hasn't felt this good in awhile. He liked the feeling of being a demon more than a human. He felt... powerful. He seemed like an emotionless killing machine who never felt love on his life. He sold his human soul to the demon and chose to live as a demon more than a human. The emotion of love, has terrified him... and now, he wants to kill the person he loved most.

A bit shocking to some people, right? Ha, now I made Klaus cold and emotionless like his old self. 3

He still doesn't seem like it though.
