Use of Extended Katakana

Mangaville Chronicles Pixkapow was a Japanese anime series created by Hashikawa Co. Ltd. on April 13, 1999 that used extended katakana and name spellings to provide more accurate tracnscriptions of the names. For instance:

ア゙/ア゚ = a イ゙/イ゚ = i ヴ = v(u) エ゙/エ゚ = e オ゙/オ゚ = o

ラ゚ = la リ゚ = li ル゚ = lu レ゚ = le ロ゚ = lo

Punctuations

・ = space ＝ = hyphen
Forms of ア
アー ≈ retroflex vowel
アァ = a longer ア that trails off; for instance, the small katakana always extends the preceeding large katakana's vowel, rendering it a more accurate long central vowel sound than its homophone used in governmental documents
Others
ンー = a longer ン
ン゙/ン゚ = n
アァ = extended katakana form of アー. It is used to separate the long central vowel from the retroflex vowel.
ー: Usually extends the vowel. All ウ-form katakana other than ウ or ヌ have to precede this special bar to have their vowel pronounced. If it succeeds an ア-form katakana, it may transform into a retroflex vowel. Names like Elgala (Japanese: エルガ(ー)ラ Eruga/āra) may be exceptions.

Fictional Interstate Highways

An Interstate (Japanese: 州間高速道路 Shūkan Kōsoku Dōro) is a highway, except for lettered ones, runs throughout the continental United States. Their system was planned by Dwight David Eisenhower (Japanese: ドワイト・デビッド・アイゼンハワー Dowaito Debiddo Aizenhawā) during his presidency. These are the following freeways:
Interstate 1 (or I-1, Japanese: 州間高速道路1号線 Shūkan Kōsoku Dōro Ichi-Gōsen), as its number implies, is the westernmost Interstate in the United States. Its southern end is US Route 101, and its northern end is at the Canada-United States border.
Interstate 100 (or I-100, Japanese: 州間高速道路100号線 Shūkan Kōsoku Dōro Ippyaku-Gōsen), as its number implies, is the continental United States' northernmost Interstate highway, and is the closest to the US-Canada border. Its multiples, like every other Interstate assigned a number greater than 100, are auxiliary. Its western and eastern ends are Interstates 1 and 95 respectively. It crosses all the Great Lakes except Lake Michigan. Interstates 200 to 800 are loops and/or bypasses of this controlled-access highway, while Interstates 300 to 900 are spur routes.
