Background
Erwin is the fifth son of a noble family who owns a village with a populace of 500. His family's financial situation is similar to Wend's and as the family's 5th son he won't inherit their wealth. So to make his living, he plans on using his sword talent (to which he trained his butt off) to pass the scholarship exam and become an adventurer (which worked very good, since he's the top of the class in terms of swords). He then met Wendelin and they hit it off immediately, becoming very good friends in the process.

Plot

Sword Talent

 * Immense Prowess - Erwin has a great prowess with the sword, evidenced by the fact that he is the top swordsman in the Adventurer's School. His prowess and potential is so immense that even the Knight Commander Warren, the champion in the Sword Category of the Tournament, was impressed and decided to take him under his wing for training.
 * Versatile Swordsman - Since first training with his wife (then fiancee) Haruka, Erwin discovers that he has much higher talent for Japanese Swordsmanship (specifically 剣術 - Kenjutsu) than Traditional Swordsmanship, but his technique is not sharp enough for 抜刀術- Battōjutsu and his reflexes are not fast enough for 居合術)- Iaijutsu just yet. This is further evidenced that he can wield a magic katana while having normal human mana with ease, showing his diversity in his swordsmanship.

Commander
