|Shadow Hearts: Covenant|
The first Wolf Bout boss, Tetsu is more of a tutorial than anything else. A young dog at a year old, he treats Ernest like his grandfather. Apparently he isn't a real wolf anyway.
- Tetsu means "Iron" in Japanese, giving this dog a deceptively strong name for his ability.
- Tetsu is one of two wolves in the Wolf Bout to share Blanca's element of Wind, the other being Mash.
