The First: Seijuro Hiko the Master of Swordsman.

Seijuro Hiko was the first magnificent character I found in anime world. He was seen in Rurouni Kenshin or known as Samurai-X, as Kenshin Himura's teacher. He was the 13th successor of Hiten Mitsurugi Ryu art of swordship style. His real name was Kakunoshin Niitsu. The Seijuro Hiko name had passed to him as the successor of Hiten Mitsurugi Ryu. The first Seijuro Hiko was the first man who mastered the Hiten Mitsurugi Ryu. Every apprentice who succeeded the mastery will bear that name. In order to succeed, one must kill the former master because there's only one people at a time who can master the style.

Seijuro Hiko was the one who taught Hiten Mitsurugi Ryu style to Kenshin Himura. The powerful technique that made Kenshin became the most fearful hitokiri battousai (assassin swordsman) before Meiji Era started. He was an orphan when Hiko found him. Hiko took him as his son and his apprentice. Kenshin was called Shinta at first. Hiko had changed his name to Kenshin, which means the Heart of Sword. In episode 41, in order to beat Shishio, Kenshin had to finished the Hitten Mitsurugi technique he abandoned years ago. So he went to Hiko's place to beg him to complete his teaching for him. During that process Kenshin had able to win Hiko so technically he became the 14th successor.

Hiko-sama is believed to be 43 years old in the story. It was the style he mastered that made him looks younger than his age. The same thing happened to Kenshin Himura, his apprentice, who had youthful look that might deceit people who did know him well. His height was more than six feet tall, weight about 87 kgs, had brown eyes and long black hair.

His daily activity was doing pottery (knowing his built, I think noone would believe he was only doing pottery). He liked drinking sake a lot without losing his mind while enjoying the 'happy hour'. He tend to avoid people's affairs as much as he can. In the story, he always make a sudden appearance as well as his quiet withdrawal from the story. He is a loner who lives in a mountain near Kyoto, it has to do with his past that made him live in seclusion.
