Rentaro and Katarina

The first official couple of LOTM: Sword of Kings and the first Katarina Couteau's relationship. Although both had feelings for each other, both were too shy to admit these feelings. In Katarina's case, she matured after the death of her sister, Eugen Katsuragi, by the hands of Aki Honda and began to discover a little more about this feeling called "love" and developed this feelin' for Rentaro Satomi.

But remember, this couple is a perfect example of what you should NOT do when you're in love with someone. If contrary... It will be too late to confess you feelings...
