I've gone to a lot of conventions (both anime and comic), but I do agree with you- it would be difficult to go to one alone. However, it's a great place to meet people with similar interests. I've met a ton of people that way (in particular several booth owners that I chat with in the vendor rooms), so you could always go and see if you could make new friends that also enjoy anime.
Black Star is from a series called Soul Eater- a really good action anime that has great fights and cool references to mythology and religion. I was particularly interested in his voice actor because one of the characters I cosplay as is from that same series. I often go as Crona- that's me in costume below when I was walking the stage for a contest.
The original image of the character is

If you want really good anime to check out I would recommend: History's Strongest Disciple Kenichi, Toriko, Onepunch-Man, Attack on Titan, Sword Art Online, and Blue Exorcist.
