"Saiki talking to the reader or other characters through telepathy"
"Saiki talking using mouth"
'Saiki or any characters thoughts'

"Hey, where are you off to?" inquired the youngest sibling, noticing their brother's attire - a stylish combination of dark and light gray sweater paired with black pants. 'Since when did he get that sweater??'. You couldn't help but wonder when he had acquired that particular sweater.

"Going out with my friends. I got this sweater last week, online." Saiki replied to your question before drinking a cup of water.

"Uhh going where exactly??" You ask him again.

"The mall-"

"Can I come with you please?!" Y/n instantly interrupted their brother as soon as they heard him mention the word 'mall'.

But after saying that they reflectively think about it again. 'He is with his friends, right?'

"Nevermind, you probably don't want me to be near your friends-"

"Go change." He interrupted

"Huh?"

"I'll be waiting right here," your brother said softly as he walked over to the couch and settled down beside the sleeping cat.

As you stood there, a mix of shock and surprise washed over you, causing your eyes to widen. His unexpected response took you off guard, but at the same time, you felt a rush of happiness knowing that he had agreed to let you come with him.

"Wait for me!"

･ᴗ･

You decided to wear a simple outfit to go out. And right now you're walking downstairs with a smile on your face from just imagining what would it feel like to go out with your brother's friend.

"I'm done!-"

"Meow..." ("Need... food...")

You hear a familiar voice below you. You look down to see an orange cat laying his back down, is he dead?"

"Anpu!"

You take the orange cat into your arms and cradle it like a baby. "Why haven't you fed him??"

"I did, he just got hungry easily."

"MEOW MEOWW" ("HE LIED. HE ABUSE ME!! ANIMAL ABUSE!") You heard the cat meowing at the same time talking.

You're not surprised anymore, ever since the last accident, weird things have happened.

For instance, you can hear people's or animal's thoughts, when you eat the spoon bends itself, random teleports,

and the most scariest of them all is-

you can see the inside of people.

Organs, blood vessels, bone.

And the worst part is-

You can't control it. It just happens randomly.

Saiki is aware of it. Though it seems like he can't even find a way to prevent it from happening suddenly.
