"...Fascinating..." Kisuke muttered with a big smile on his face as he intently stared at Medusa's purple-jewel like eyes with rectangular pupils.
It took Medusa a few seconds to respond due to how unexpected his response was, "Huh...?"
If she didn't know any better, she would think that her mystics eyes became normal eyes. But then again, she wasn't so sure anymore and checked it. The results just gave her more confusion as she knew that her eyes were working properly... sadly.
Kisuke didn't mind her reaction and kept staring straight to her eyes. Kisuke can feel his blood flow slowing down significantly if he didn't try to resist her gaze. As an experiment, he stops resisting her power on the index finger of his left hand. The petrification started from the blood before going to his muscle tissues until it reaches his skin.
Medusa was finally aware that her gaze isn't affecting him in any way. Inside, she's feeling happy at his apparent immunity, but she's still worried about him knowing her real identity. Because of the way he's acting, she didn't know if Kisuke already has a clue or not, but chances are he didn't know as she's confident that he would make a disgusted face if he knew. So, with much hesitation, she asks to confirm, "...Aren't you afraid of me?"
Kisuke's still staring at her as he answers, "Why would I?"
Medusa gritted her teeth and said, "...Because of my identity..." She closes her eyes and waited for his answer.
Kisuke raised his hand on her forehead and flicked it.
"Ow!" Medusa was startled. She raised her hand to cover her forehead and looked back at Kisuke who has a cheeky smile, "What identity? Aren't you Ana? Did you read too much fantasy book that you developed a chuunibyou case?"
Her eyes widened at his answer, '...He knew...'
"...Why?" Medusa asks while she stares back at him.
"What do you mean why? I'm too busy to go along with your antics" Kisuke still pretended that he knew nothing, but it was too obvious for Medusa.
"Pfft..." Medusa felt compelled to laugh. She already put down her worries and felt relieved.
"You're weird..."
"I don't want to hear that from you!" Medusa retorted at his words as he is not qualified to label others weird, "Thank you..."
"Enough with that and let me take a look at your eyes more." Kisuke fixed her head in a position where he could easily examine her eyes from different angles.
With her nervousness and worries gone, Medusa's mind finally caught up to what's happening. Their faces are only a few inches apart and she became extremely conscious of him. More so than normal because she has trauma and complex with her eyes. A few more seconds of staring contest has passed and Medusa's face is now dyed red. Due to embarrassment, she covered her face with both of her hands as she can't take his stare anymore.
"Oi oi... What are you doing? I can't see your eyes if you cover them up."
"...Please don't stare at me... It's embarrassing..." Medusa bashfully muttered in a very low voice but Kisuke, who is in front of her managed to catch it.
"What? I've been staring at you for a while now, and only now you're getting embarrassed?"
"...Please forgive me..." Medusa pleaded for mercy while still covering her face. Her ears were beat-red remembering what happened earlier.
"For a cool beauty, you sure get shy about strange places."
"It's not strange!"
"Well, whatever. I'm done anyway." Kisuke then examined his petrified finger.
Medusa felt his gaze moving away from her and uncovered her face. But what she saw almost gave her a heart attack, "Your finger!"
"Ah... Don't worry about it... But really... This is amazing. I can't revert its effects. I have to study the process of petrification and the composition of the petrified part." Kisuke then started muttering to himself.
Without regard to his reaction, Medusa suddenly stood up and grabbed Kisuke's hand with a petrified finger and touched it gently, "... W-what should we do!?"
If it's just in the semi-petrified state, Kisuke's Mana inside his body could automatically heal it as long as the source of petrifying ability was cut off. But a completely petrified part like this is impossible to heal from her knowledge. Even the greatest heroes in the past died with their bodies petrified. She doesn't know if a God can reverse it but she's sure that Kisuke is a human and doesn't have a God's physique.
"Nah... Don't worry about it." Kisuke took back his hand and to Medusa's shock and dismay, he suddenly broke off his finger effective cutting it from his hand. Due to this, Kisuke blood splurted out like a mini fountain.
"What are you doing!? Are you insane!?" Medusa hurriedly grabbed his hand back with one hand and the other one tore her shirt to get a piece of cloth. She hurriedly wraps it around his hand to keep the blood from flowing out, "What are you spacing out for!? Hurry! Use some healing magic to stop the blood flow!"
Kisuke ignored her instructions and asks, "I'm glad that you're worried about me, but you didn't strike me as the protective type."
"What the hell are you talking about now!? This isn't the time! Ah... This is my fault! I shouldn't have agreed to this! Because of this mistake, you lost your finger! And why is your finger the only thing affected?" Seeing that Kisuke isn't doing anything to heal his wounds, Medusa then crudely transferred her Mana to the stump of the severed finger to temporarily stop the blood flow.
Kisuke wanted to poke more fun from her, but seeing her worried expression, he stopped himself and patted her head, "Thanks... And as I said, don't worry about it." Kisuke then separated from Medusa, "Ah!"
Without waiting for her to move further, Kisuke discarded the cloth soaked in blood and suddenly donned his hollow mask.
When the bone mask with green marking suddenly appeared, Medusa stopped herself from chasing Kisuke. She noticed that his eyes changed along with his aura. She took a step back as Kisuke's current aura is very malevolent. She didn't know what to do aside from watching him.
In the part where his former finger is placed, Medusa noticed a white matter bubbling out and after less than a half of a minute, it formed a white claw-like finger. Kisuke put his hand on his mask and it disappeared as he swiped up. And the claw-like finger suddenly cracked with its shell-like structure falling down revealing the new finger inside it, "See? You don't have to worry~." Kisuke then showed it in front of her and Medusa unconsciously grabbed it to examine it, "...How?"
"One of my tricks~." Kisuke then took another look at the petrified finger and said, "This is a good specimen... I have to go and break this down into pieces." Without waiting for her, Kisuke hurriedly exited the room to experiment.
"...What is that all about?" Medusa muttered to no one.
