The Best アニメ older sibling to me,is Mr.Kaiba from Yu-Gi-Oh! (he's the older brother of Mokuba),he's not very friendly with Yugi-boy and his friends,however when it comes to Mokuba he'll do anything for him,he acts もっと見る than friendly to him,I find it that he's もっと見る family oriented than friend oriented (I don't he acts the way because of the money and because he's rich,I think he acts that way because he feels having フレンズ would change his relationship with his brother!),so I really like Mr.Kaiba as an older sibling he really does care for his younger brother!
