Asakawa Yuu 浅川悠
I love her. Not only because she provided her voice for Luka, I like her other work too. I love Sakaki form Azumanga, Kusakabe Misuzo from 11eyes, Shinonome Satsuki from Koi to Seknkyou to Chocolate or Leone from Akame ga kill to name a few. Still have to pick up some anime or games she voiced like Fate.
I also love her singing voice, some times even more than Lukas voice.

Otaku Verse Zero
Was a webshow running from 2010 to 2012 with 3 seasons.
Some episodes are interesting are boring, especially the first season is weak. Would recommend watching season 3.
Yuus English is not the best but it's kinda cute.
Social networks
She writes most of her tweets in English. Some times she tweets about her work, some times about drinking with friends and some times how moch she loves Leon from Resident Evil. Some how ironic that she kinda has a Husbando.
