Ren and Kyoko had gotten to know each other better after their constant run ins they formed a sempei/kohai relationship,one day at LME Ren had just finished tea with the president when he saw a terrified Kyoko shaking and paled walking listlessly in the halls shocked at this he had never saw her so horrified, he saw her happy,angry,embarrassed,gloomy but never so horrified to the point where she was shaking and pale.
"Mogami-san whats wrong?"he said his worry increased when she looked at him tears in her eyes and grabbed his shirt.
"he found me,he's gonna kill me Tsuruga-san please save me"she said just before passing out Ren filled with worry picked her up as fast as he could and rushed her to the hospital calling the president and Yashiro to cancel his upcoming appoitments,the doctor let her rest and went put to a worried Ren.
"how is she?"he said looking at the doctor eyes filled with worry.
"she'll be fine she just passed out due to large amount stress when we gave her a MRI we found several fractures nothing life threatening after all they have appeared to be healing is her home life alright?"the doctor worried about why this girl had these injuries,Ren frowned although he spent a ton of time with Kyoko he only knew one thing about her home life and that was she moved into darumaya before joining LME,Ren hated how she knew alot about him but he barley knew anything about her.
"no i don't"he said depressed the doctor sighed and patted his shoulder and left the actor alone with Kyoko who was tossing and turning in her sleep,Ren tried comforting her but when his hand touched her face she startled him by quickly jumping off the bed hiding in the corner in the fetal position.
"Kyoko?"he said shocked at what happened,she turned to look at him eyes blurry and scared,after looking around she blushed awkwardly and bowed to Ren.
"i'm sorry Tsuruga-san i didn't mean to startle you that was just a old force of habit"she said as she stared at his startled face,Ren twitched and he stared at Kyoko with his demon lord aura.
"Kyoko, tell me what's going on right this instance" he said and he watched her flinch at his aura she knew although Shotara had a bad aura this man's aura was a thousand times worse.
"i don't want to talk about it"she said and looked at him her eyes pleading him not to ask anymore but he refused to falter all though he almost did until she caved first and she told him the whole story.
'THAT BASTARD I`LL FUKING KILL HIM' Kuon thought but Ren just simply replied "so that's why you asked me to save you?" he said his other self running rampant,she just nodded and he sighed,never had he wanted to kill anyone as much as Shotara at that moment.
"i`ll talk to the president about it he'll know how to deal with it"Ren said barley containing his temper.
"don't what if he finds away to still get to me?"she said still terrified,Ren rubbed her arm noticing her twitch.
"its alright Mogami-san i promise i won't hurt you"he smiled at her she knew she could trust him since he was nothing like Shotara who was violent and evil,no Ren was kind and warm.
"i trust you"she finally said causing his mask to slip and showing her his true smile.

they can be identified cause demons are able to teleport and have a menacing aura while angels have a powerful healing ability and the only girl angels in this are Julie and Kyoko
