It's been a while since you join the Techo club, and the Doberman Beastman or Jethro being the head of the club.

As always, you entered the club and sees him slumped on his chair desk.

"Oh, you back." His ears twitched at the sound of your footsteps. He glance at you, taking the seat beside him.

"I'm making this," He slide a blueprint to your desk. Then Jethro looked at your face. "I want to create this kind of interesting thing."

It's a kind of pen that could shot a sleeping dart stick.
