Sanae Kirishima, also known for his pseudonym The Frog or The Frogman is the main villain of Ryousuke Tomoe's horror manga novel Museum: The Killer is Laughing in the Rain, better known for his appearence on his 2016 horror-thriller adaptation Museum. He is an highly dramatic and meticulous serial killer that was believed to be taking vengeance for the sentence and suicide of Shigeru Ôhashi, guilty of the Girl in Resin murder case. But as the story progresses, we soon realize that his motives were even more darker. He was portrayed by Satoshi Tsumabuki.

Appearence
Sanae is a tall man that always wears a blackened-greenish oilskin with the hood always opened up and jean pants with black rubber boots. A rubber frog mask with frog-themed gloves is a frequent motif on his outfit and always wear it as a form of covering his skin from the sunlight, as well as hide his identity. Without the mask he is a bald man, and his skin is covered with scars and sores product of his photodermatoses. His voice his very high-pitched, specially when he is laughing, and his face is seemingly flattened.

An Artist is Born
Both on the manga and movie his origins remains almost the same:

Sanae was the son of an art dealer called Eiji Kirishima, who along with his stepmother, Keiko, were brutally dismembered by an unknown murderer, and all of his pieces were reassembled as they were one person.

In the film, he had a sister, named Mikie, who was taken by a medic and raised as her daughter, while Sanae was left very young alone to a clinic to trait his photodermatoses (a skin disease that causes painful sores when exposed to sunlight). He passed alone all of his childhood, remembering the gruesome crime scene that he found on his own house, until years later Mikie found him, already titled as a reknown medic, and took him to an specialized hospital were they treated his disease. However, this didn't take long enough as Sanae leaved the hospital and returned to his old home were the murder of his parents took place. The old memories of him finding their bodies, leading to Eiji's profession as an art dealer ending up growing a deep trauma on Sanae's mind, making him wanting to be a great artist that wants to be remembered on history. However, Sanae replaced the brush and canvas for something more peculiar: People

Personality
Kirishima can be described simply in one word: Monster

Despite having a very well developed psychosis that has been growing on him since his childhood, Kirishima also showed traits of taking joy on the pain and misery of others, both psychologically and physically, making understand that he pretty much understands how human mind works. He loves making his victims suffer, not only by subjugating them to very complex and painful tortures, but also making them known that they are going to die at his hands and pointing them their reason of 'punishment', leading them to terror, guilt and panic, that leads Kirishima to frequent outburst of excitement. However, his psychosis obligates him to find a work on his murderous enjoyment, reason why he view his kills as 'art' pieces, and makes him adopt the current traits of a pompous artist that loves to drag attention.

He has a really strong sence of artistic flair and likes to make very complex and well prepared (but still gruesome) crime scenes, with the intention that the police will find it and the media will label him as the 'artist' he is suppossed to be. He possess an extreme cunning an intelligence that helps him on his murders: He is extremely meticulous on every little works he does, stalking his victims, investigate every single aspect of their lifes, making little plastic models on how the murder will look, how it will be made, where it will take place, etc.

Kirishima is a nihilistic being that views no purpose on being alive, not even by himself. He views people as vessels of terror that he exploits to bring himself pleasure, as he takes fun on the misery of people. However, he also knows that he will die someday and the fun will not last forever, reason why he wants to be embodied on history as the supreme artist that will live forever on his gruesome works, and thus, will live forever on the collective consciousness of people.
