Known as the "Jewel in the Capital's Crown," the Peninsula Manila has become a landmark in Metro Manila because of its majestic fountain in front of the hotel.

The iconic fountain and the street signs of Ayala Avenue and Makati Avenue took centerstage in the Detective Conan: Black Iron Submarine film. 

Some stills from the movie posted by Detective Conan PH: Anime and Manga featured the buildings and skyscrapers of Makati with the Japanese translation of Manila, Philippines. 

A short synopsis was also written on the post about why the main character of the film Vermouth was in the Philippines. 

"The story behind this goes back to when Vermouth flew to the Philippines and took her stay specifically in The Peninsula Manila Hotel at Ayala Avenue, Makati City, to carry out her plan to help Ai Haibara in return for her good deed.

When Vermouth knew that Haibara was captured, she immediately thought of a plan to help her.

Vermouth traveled to different places, including the Philippines, and disguised herself as Sherry to get rid of the organization's suspicion and make them believe that she was not actually Sherry -- that it was a mistake." 

Detective Conan is a Japanese detective manga series written and illustrated by Gosho Aoyama. It talks about a prodigy lawyer named Shinichi Kudo, who inadvertently shrunk into a child's body after being forcibly poisoned by a crime syndicate. 

Shinichi assumed the identity of 'Conan', who uses his detective skills to solve mysteries while determining the reason behind his condition.
