How to complete Lamentation From The Shadows in Tribe Nine. Informants are well hidden
Tribe Nine has a number of interesting quests, and one of them is Lamentation From The Shadows. Here you will learn where to find informants and how to complete the mission.

Tribe Nine is a free-to-play gacha game in which, in addition to exciting battles (yes, the Shark, we are talking about you), exploration and completing missions are also important aspects. Not all objectives are easy though. One quest, namely Lamentation From The Shadows, is an excellent example of a task which causes problems. It involves finding two Informants. However, they are very well hidden, so if you have trouble locating them, this guide will tell you where they are.
Tribe Nine – How to complete Lamentation From The Shadows quest
Lamentation From The Shadows involves finding two Informants in Shinagawa City, who are “at a high place” and “a place where junk gather”. As you can see, those clues are not very accurate.
The first Informant, who is hidden “at a high place”, is located in a Hotel. Move to it and then use the elevator. Choose the highest floor, which is the 40th, and when you get there, head to the right. There you will notice an NPC who is initially called ???, talk to him. He asks if you agree with the statement that high places are nice. Answer that you do.
To solve the second puzzle and find the hidden Informant, open the map and head east of the Hotel, looking for the Junk Storage location. Enter the building on the left side of the map. Go inside and talk to another NPC named ???. Select “Yes, I do” option and listen to what this character has to say.
After gathering all the information you need, report it to Worried Woman. She is located in the Execution Plaza. To get there, move to Shinagawa Central Avenue, take the escalator up and go to the new location. The woman is situated north of the entrance, on the left side of the circle.
