This is actually part 4 of the Big Talk series (like the description says), you'll need to read its 3 prequels first before getting the story.
After reading all of them (including the extra), I have to say, this is one of best Shizaya doujins out there :D
The prequels (and extra) are: Taigensougo de Sora ga Ochi (there's part A and B) Ryuugenhigo de Umi ga Ware Yomotsuhirasaka Kimi to Koe Good-bye Blue Bird is the extra which suceeds this chapter and is basically the whole series from the POV of Izaya.
Soltarination translated the rest so check them out!
