Kaito walked down the stairs with caution. He did not switch on the lights because he did not want to alert the enemy about his location. Furthermore, he was quite comfortable with the darkness because it allowed him to depend on his other senses.
If someone had managed to bypass the security system and the guards stationed around the property, they had some skill. He could not afford to be careless.
When he was walking down the stairs, he noticed a person standing beneath the stairs. The space was usually empty, so it was a good hiding spot. The person probably planned on waiting for someone to come down and ambush them.
Kaito lifted a simple needle with a paralytic poison and aimed at the person. He did not intend to kill the intruder without asking a few questions, but he would not be overly concerned if they died before he could deal with them.
