Personality (2)

Almost immediately, Ruka becomes attached to Mikan due to her cuteness and cheerful personality. He makes attempts to befriend her and understand her, even if he thinks Natsume will oppose, after noticing that the academy is, too, targeting her. He tends to blush when he sees her in cute clothing or when she says soemthing cute. While his feelings become that of romance, it makes him vulnerable for his fan club to tease him. When they realize they both love Mikan, Ruka and Natsume have a sort of rivalry over Mikan and both say they don't want to lose to each other. He even asked her if she would like to switch Alice stones with him during the Z arc, even though she didn't understand the meaning of the switch then (the switchers would be soulmates). However, while they look into Yuka's past, he discovers that Mikan and Natsume's mothers had been best friends and Nodacchi commented how of a miracle it was for Mikan and Natsume to meet in the academy. This makes Ruka realize that Mikan and Natsume were meant to be together. Telepathically, he allows Natsume to be with Mikan because Natsume needs Mikan and she needs him. He admitts to Mikan that he loves her but he tells her that Natsume is the only one for her and he will support them because he loves them both very much. Natsume returns this later on by trusting Ruka enough to protect Mikan in case he dies in the near future.
