Devising duct tape seals with Eva after dinner [EP5] Form of a golden stick. (Snap it/unsharable.)

"......Allow me to explain. This is what I sealed the doors with. ......Did you think this was paper, Battler-san?"
Erika once again held up the thing that looked like brown paper.
"This is duct tape. Its adhesive power is extremely strong. ......I used scissors to make it easier to tear."
"Furthermore, I wrote my signature, which cannot be reproduced, across the entire tape, as well as the door and the frame on either side. Therefore, it's impossible to tear it off without leaving a mark, and it's impossible to reattach too...!"
"Permission to unsheathe the 'Red Key'."
"Granted."
"Due to the above, the seals are guaranteed to be PERFECT. <Miss> Erika's seals were not broken by anyone, and deception is IMPOSSIBLE!!"
"I'll acknowledge Erika's seals...! However, Eva oba-san's seal on Genji-san's room should be different!!"
"Eva's seal was of the same type as <Miss> Erika's. That is because this method of sealing was one that <Miss> Erika and Eva conceived of together after DINNER."

^ She's not remembering that, just remembering doing the actual conceiving. Probably she talks to Eva about mysteries and closed rooms and such, Eva mentions her method of sticking a receipt in the doorframe so you can tell if anyone leaves, Erika says there's ways around that, and eventually they come up with this method! That's all.

Effects
- ♥ duct tape.
- more unreasonable reactions to mysteries
