Suteki Tantei Rabirinsu (Fantastic Detective Labyrinth 03)

Fantastic Detective Labyrinth 03 - Adventure in the Leaning Tower Minori asks Mayuki to fix a special souvenir for her, a birthday present from her father a long time ago. Mayuki reluctantly explains that he can't and wishes that he could, but he can't. Kouta has spent most of the day fuming about how everyone at school--particularly the girls--are fawning over Mayuki. Rakuta suggests a plan to him and Kouta shows up, declaring that he will venture into a no-trespassing zone to find Minori a new souvenir. At the last minute, everyone but Yaya-chan decides to go to the abandoned Tokyo tower where things mysteriously turn weird.
