In some ways, Tsuneo was the least problematic of the main cast. He had a well-defined role, he had a well-defined personality and he definitely had provided us with a lot of good material. In many ways, he would be the least changed of them, but still required some work.
Tsuneo at heart was a fanboy, albeit a smart one. He was the one who liked a series for its themes and concepts and bigger ideas, not because it was full of, say, giant robots blowing stuff up. He also had a nice thing going where he would be a fan of the obscure, the off-beat and the alternative, stuff that might not be easily recongised and, as such, provided an opportunity to do some jokes that wouldn’t work otherwise; his love of Brain Powerd being a very good example.
Likewise, his tendency to get easily riled worked well for us, with Tsuneo’s rants becoming the stuff of legend and running gags. Many times he would explode outright, which lead to extreme measures to get him under control. Other time, he would be the opposite, acting as the voice of reason and the mature one (despite being the second youngest of the cast), helping reign in the others when they went nuts or were veering wildly off-course. “Don’t go there” was as much a catchphrase as many others.
