I realized this today; 

You know how the japanese version of P4 implies that Naoto is a closet-fan of the Sentai franchise and how the artbook says her Persona’s design is based on Kamen Rider?

Well, today I figured something out:

The Sentai Series that came 2000 was “Timeranger” (Adapted into: “Power Rangers: Time Force” in America). It’s Sixth Ranger was named “Naoto Takizawa”.

The Sentai Series that came 2001 was “Gaoranger” (Adapted into: “Power Rangers: Wild Force” in America). It’s Sixth Ranger commonly went by the name “Shirogane”. 

Naoto’s name is a combination of two consecutive Sixth Rangers, both of which were lone-wolf type characters. 

Just like Naoto herself is a lone-wolf type “Sixth Ranger” to the IT!

Those magnificent developer-bastards!!!
