Kamonohashi Ron no Kindan Suiri - Season 2

There's been a murder in Shibuya. A man has been found killed in a ghastly and impossible manner. Toto and Amamiya arrive at the scene to find Ron already there. A mysterious message makes them wonder if there's more to the crime than meets the eye.

There's been another murder in Shibuya. Shocked by the death, the victim's teammate runs. Ron and Toto race to catch him and find more information on the culprit picking off the hacker team. But the more they find, the more complicated things become.

A huge monitor across the street explodes. While Ron and Toto try to make sense of events, Winter tells them that they've lost more than they realize. As Winter torments Ron with the guilt of his failure, Ron realizes that Winter is hiding something.

Toto suggests that Ron take a rest. They invite Ron's doctor, Usaki Mofu, along and head for a dip in the ocean. Ron looks forward to having shaved ice with black sugar syrup from a beachside stand, but things soon take a tragic turn.

Ron and the others interview witnesses, but everyone has an alibi for the surfer's estimated time of death. They can't find any concrete evidence that indicates who committed the murder. Then Mofu's usual clumsiness leads to an unexpected clue.

Ron accompanies Toto to the concert of a super popular artist Nyonyon. After the performance, a card is found in her room. It's from the Talent Abductor, Hummingbird, who has been taking geniuses of all types one after another.

Nyonyon has disappeared. No matter how much they search the house, there's no sign of her. Sannou presents his personal deductions and concludes that Hummingbird is actually there among them, but Ron spots a hole in his reasoning.

A lack of cases has left Ron bored, so he and Toto go with Chikori to gather information for a story she's working on. They visit a university lab researching cognitive psychology where the air is filled with hostility.

Ron and Toto present their deductions to Professor Aoe and the students who use the lab. A number of inconsistencies, starting with the postmark on the threatening letter, lead to the killer's identity and the selfish reasons for their crime.

Ron and a number of other guests have been invited to Reunion, an auberge located on a verdant plateau. When their multi-course dinner is served, Ron notices that most everyone seems uneasy. The next morning, there's a disturbing discovery.

A second victim is found. Ron notices a pattern in the murder scenes and decides that the key to the mystery must lie there. It soon becomes clear that the guests who were upset by the food the night before are all connected to a case from the past.

Ron is in a state of shock after a staggering revelation. He shows no reaction when a third murder occurs. Toto investigates, dragging Ron with him. When Ron recovers enough to help with the case, he tells Toto what he's decided to do.

The culprit behind the killings at the auberge has been identified, but Ron is still reeling from the flood of memories that this case has triggered. Will the missing pieces of his past bring him despair, or something else?
