Crossover: I Took In a Runaway High School Girl

Mai Sakurajima's issue was merely a small episode in Renji Kamisaka's daily life. He smiled softly and shook his head, then turned and returned to his room. The mysterious treasure chest in his room hadn't been used that day.

When Renji wasn't using it, Frieren from another world was conducting experiments. There were at least three chances a day to put items in and receive rewards. Sometimes, strange items would appear. For instance, magic potions, sometimes they were potions to replenish magic, sometimes magic potions to enhance magic. These potions were very useful for Fern, Frieren's disciple. Frieren herself didn't need magic potions, but they were good for research and adding to her unique collection. And occasionally, plants from another world would appear, with unknown properties. Of course, Renji Kamisaka gave all of these to Frieren. Don't let her lazy appearance fool you, once she got into research, she would become incredibly serious. An elf's concentration was incomparable to a human's, as if time itself stopped around her.

Looking at this treasure chest, Renji Kamisaka remembered that the last time a treasure chest monster appeared, he had thrown in instant noodles and soda. Now, seeing half a bottle of Frieren's leftover Coke on the table, he tossed it directly into the chest.

A bright golden light flashed from the treasure chest. Renji Kamisaka immediately showed an expectant expression. Based on his experience opening boxes during this period, different lights would yield different rewards. Golden light and red light were both very, very good rewards.

[Ding, the treasure chest has received a reward.]

[Ding, congratulations to the host for receiving the reward: Angel's Blessing.]

Renji Kamisaka's mouth twitched. Angel's Blessing? Would it be "Gabriel's Panties" again? His mind drifted to previous experiences.

Opening it and looking at the contents, he was surprised to find that it wasn't panties, but a pure white bra. He immediately checked the object's information.

[Angel's Blessing Bra Version: Angels who grow too quickly often face situations where their size is too small and they will pop open. So the angels blessed it, making it hard and retractable, with the holy breath of angels and the effect of warding off evil.]

[Evil-warding warning: Any evil creature will flee without hesitation upon encountering it.]

Seeing this, Renji Kamisaka was truly surprised. I didn't expect this bra to also have an evil-warding effect. He chuckled. It was good to give as a gift. If the walking magic panties last time belonged to Gabriel, then this one now... couldn't it be Gabriel's best friend, Raphael? According to the information, only she would have a situation where her body was too well-developed and bra clasps would pop open.

Renji Kamisaka casually placed the bra in a drawer, and he began to think about who to give this unique item to. The evil-warding effect was still very good, it could be useful for someone.

There were two more chances to open the box. However, no special items appeared. The first was a fox mask, which seemed to be just a decoration. The other was 50 blank talisman papers.

Renji Kamisaka found that as long as the magic power brought by the demon dragon physique in his body was injected into the blank talisman paper, it would have some flame patterns. He tried throwing it into a flower bed in the yard, and the talisman paper quickly ignited, then turned into black magic flames that instantly blasted the flower bed into smithereens.

Renji Kamisaka immediately understood the value of the blank talisman paper. What a good thing! It could actually store magic flames for attacking. And it was long-range. His combat potential increased drastically.

After opening the treasure chest and taking a shower, Renji Kamisaka prepared to visit Shiina Mashiro that night. Suddenly, his phone rang. He clicked it, and it turned out to be Yotsuya Miko calling.

"Hello, Yotsuya, what's wrong? Calling so late?" Renji asked, his tone slightly anxious.

The voice on the other end of the phone was trembling and choked. "Um... Please, Kamisaka, I encountered a super terrifying presence."

Well, Renji Kamisaka knew it after hearing her say that. Miss Miko must have met a terrible evil spirit again. "How can I save you? I don't even know where your house is, or where you are now?" Renji was a little confused. "It's already very late..."

"Wuwuwu, I'm at home, please, come and save me!" The girl held back her tears, clearly she was scared half to death.

"What's the situation now?" Renji pressed, trying to get information.

"Wuwu... That presence is staying with my mother and won't leave. My mother was sick yesterday. I feel like taking my mother away. Please, Renji, come to my house! Help me." Her voice broke, despair clearly audible.

"Alright, wait a moment." Faced with the crying plea of the beautiful girl, Renji Kamisaka naturally couldn't refuse.

"Thank you!" After Yotsuya Miko expressed her gratitude, she quickly reported her home address.

Renji Kamisaka hung up the phone, grabbed the magic bra and talisman paper he had just acquired, then hailed a taxi to the destination.

An hour later, he arrived at Yotsuya's doorstep. He got out of the car, pulled out his phone, and called Yotsuya. "Hello, Yotsuya, I'm at your door."

"Alright, I'll open the door," Miko replied quickly.

As the door opened, a girl dressed in pajamas appeared before him, her eyes red and swollen. Without time to say more, she eagerly grabbed Renji's hand and pulled him into the entrance. "My mother is on the first floor. She's sick now. I really suspect that thing is causing the problem. My mother's skin is getting worse, but I can only watch and can't do anything." The girl said, her voice choked with emotion. The feeling of helplessness in the face of this unknown existence made her extremely uncomfortable, even nauseous.

Renji Kamisaka couldn't help but raise his hand, touch Miko's hair, and comfort her, his voice full of calm. "Don't worry, I'm here, everything will be alright."

"Yes, thank you," Yotsuya Miko rubbed her wet eyes, took his cold hand, gently opened her mother's room, and walked in.

Renji Kamisaka also got a notification immediately after that.

[Ding, a high-level evil spirit has been detected, the spirit eye has been activated, and the special effect attack effect of the spirit eye has been recharged. Ding, the player has a special attack chance with the spirit eye. Do you want to use it?]

"Not for now." Renji decided. At least observe first.

When Renji Kamisaka entered the room, he saw a woman who looked a little like Yotsuya Miko, as delicate as jade, lying on the bed, frowning, with cold sweat on her forehead. And beside the bed, floating in the air, was something with a dense black aura all over its body, a strong and horrifying body, and a head made of unknown bones. Fiery red eyeballs and a large drooling tongue gave off an unimaginable sense of oppression and fear.

At this moment, it stood beside the bed, and from time to time, black malice glided over the woman's cheeks, causing her to turn pale and grow weaker. No wonder Yotsuya Miko was so panicked. Normally, she could pretend not to see it to avoid danger. But now her mother was being attacked, and her life might be in serious danger. In crippling despair, she had to beg Renji Kamisaka for help, the only one she knew who had a connection to this invisible world.

"How is it? Can it be solved?" Yotsuya Miko looked at him with teary eyes, her gaze full of both hope and fear.

The arrival of the two made the dark and horrifying figure visibly wary. It leaped in an instant, extended its terrifying claws, and tried to touch them with deadly speed.

Renji Kamisaka immediately used his spiritual eye's special effect attack.

Ding, the spiritual eye special effect attack has been launched.

A bright white light flashed before his eyes and violently struck the dark figure. "Gah ah ah ah!" The evil spirit was instantly thrown to the ground, and the black aura on its body dimmed slightly, emitting a sound like steam hissing.

But it immediately struggled to get up, its body trembling, and roared at the two with its bloody mouth, revealing a row of sharp teeth. The wind whistled and a nauseating stench filled the room, making Yotsuya Miko so scared that she instinctively hid behind Renji, her face pale. This was the first time she had faced the malice of an evil spirit directly, without being able to pretend not to see it.

Renji Kamisaka frowned at the pungent stench. After he could no longer hold back, he raised his hand and cast a magic flame from the talisman he had obtained from the treasure chest.

The evil spirit, so arrogant and ferocious just moments ago, now let out a terrible sizzling sound after being hit by the black magic flame. The black gas that formed its body also burned rapidly, emitting a disgusting smell of burnt flesh.

"With a crack." A cracking sound was heard.

The horrifying skull instantly cracked, and a familiar figure known to Yotsuya Miko fell to the ground. It also screamed in pain, its voice no longer a monstrous roar, but a human wail.

"Ow! It's so hot!"

Yotsuya Miko's eyes widened, shocked and disbelieving. "Father?!"

Renji Kamisaka quickly extinguished the magic flame after hearing the cry, no less surprised himself.
