Yoyagi Park

**Yoyagi Park** (代谷木公園, *Yoyagi Kōen*) is a location featured in *AI: THE SOMNIUM FILES - nirvanA Initiative*. It is the real world counterpart to the Somnium world Novel Ingress.

## Story

This park in the Shibuya District is a favorite haunt of Lien Twining. During the day, you can see some citizens resting here.

A machine shed is placed in the park, which was used to control the fountain pump, but it has been out of use for a long time.

Yoyagi Park has been in use since at least 2010, when it was the favorite place for Bibi and Kizuna Chieda when they was young.

In the case of Half Body Serial Killings, the culprit placed the left half of Chikara Horadori's body at the stone monument in the park on February 12. Early that morning, a witness called the police after discovering the body, and ABIS agents came to investigate, and through the obtained clues, they found the balloon placed by the murderer Tearer in the old computer room and a note hidden in it.

In Gen and Amame Route, on February 15th, 6 years later, a group of people including Gen Ishiyagane, who was regarded hostile by the police, and Mizuki Date, who was as a traitor, escaped from Golden Yokocho during the chase of Special Assault Team and came here, hiding in the machine shed. Surrounded by SAT, Kaname Date tried to get everyone to surrender, but Amame Doi resisted arrest, took Mizuki's Evolver MC and fired a flashbang. Under the suppressing attack of SAT, Gen died while protecting Amame.

## Design

Yoyagi Park consists of three parts: ponds, green spaces, and walkways. The pond is divided into a larger part and a smaller part, with three small islands in the pond, and a bridge crossing the narrow area between the two parts for pedestrians to cross. Fountain is set beneath the water surface.

An information guide post is placed next to the sidewalk, and there is a large concrete area in the center of the park, where concrete and wooden park benches and vending machines which provides ALFREE are arranged. In the center of the concrete area are three rectangular pools with fountains and a rectangular black stone monument.

In addition, this area is also equipped with a machine shed for regulating fountain pump, but it has no longer been used for a long time.
