Doesn't Senpai just mean someone referring to a upperclassman? (I only know this due to the of Tokyo Mew Mew's Honorifics Explained part of the Manga so this might be wrong.) So maybe use -[Blank] because it says here it's used for family, spouses or very close friends. (But I could be wrong) Also Taro is very bland, yet he can attract nine female (Not including his sister because no). He's like one of those blank slates from those harem animes. I would prefer a good character that I can't relate to than a character I can relate to but they're bad. I mean look at Taro's Personality. "An Average Student. \ Average grades, average looks, average life... \ I’m not sure what you see in him." Like I don't know either. I heard that women like men with a sense of Humor. I prefer him to be in the gardening club.
