Editing Ghost Hunt:Volume8 Translator's Notes (section)

==Chapter 12==
===Exchange===
交換 - koukan: I think, in this case, Bou-san is using this to mean telephone exchanges used in old telecommunication systems where a human operator would interconnect (switch) telephone subscriber lines to establish calls between subscribers. Meanings also include: exchange, interchange, switching.
===Shimauma Panda Rakko===
シマウマ・パンダ・ラッコ - Shimauma Panda Rakko: Random animal names that abbreviate to SPR. Shimauma = Zebra; Panda = Panda; Rakko = Sea Otter; This wouldn't abbreviate properly in English.
===Niichan/Neechan===
兄ちゃん / 姉ちゃん - Niichan/Neechan: These are familiar forms for addressing your older siblings. Niichan is older brother and Neechan is older sister. As Bou-san said, English speakers generally just call each other by their given names or a nickname.
===Oliver===
オリヴァー - Orivā: When John speaks here, he says Noll and Oliver in English, then he pronounces Oliver in Japanese as Orivaa. The Japanese 'R' is different from the English 'R'.  ‘L’ as well as ‘R’ in English is usually transcribed as a Japanese ‘R’. To pronounce the 'R', the tip of your tongue lightly touches the roof of your mouth behind your front teeth.

===Oliver Davis===
オリヴァー・デイヴィス / オリバー・デイビス - Orivā Deivisu / Oribā Deibisu: Here, Bou-san is discussing how you would pronounce Oliver Davis in Japanese. It seems like using the バ(BA) and ビ(BI) syllables is more natural than using the ヴァ(VA) and ヴィ(VI) syllables, which involves changing the ウ(U) syllable to a ヴ(VU) using dakuten (the two dashes on the upper right of the character) and then using the small characters to specify the vowel part. Additionally, the 'U' in 'SU' is often times silent, so you end up with an 'S'.
===Peter Hurkos===
ピーター・フルコス - Pītā Furukosu: Peter Hurkos was a Dutchman who allegedly manifested extrasensory perception (ESP) after recovering from a head injury and coma caused by a fall from a ladder. He apparently went to Japan at some point. 
===Naru===
ナル - Naru: Here, Bou-san says that he heard (probably from John) that ナル is an American pronunciation. Perhaps he means that Noll as it sounds in Japanese is an American pronunciation of that nickname. For this reason, I'm leaving it spelled as Naru. Again, a Japanese 'R' is not like an English 'R' and can even have an 'L' sound. So, it's not a hard 'R' sound like NAR-U, but broken into its syllables NA-RU with the 'R' being pronounced by touching the tip of your tongue lightly to roof of your mouth behind your front teeth.
