There is a scene in one of P2's many awful dungeons where Tatsuya will save Maya from something falling on her head...but in an exact copy of that scene later, he lets Eikichi get his skull caved in. Therefore, I dub thee NOT Best Bro. In fact, I think it's pretty obvious who Tatsuya's best bro was. About as gay as Yu and Yosuke but they didn't cut it.

Also Junpei is a pig to my FeMC. He's just falling further and further the more I play of P3.

Yosuke is always supportive and cool.
