Tifa is 20 years old, and one of Cloud’s childhood friends. She is also a key member of the rebel group AVALANCHE. She holds a grudge against Sephiroth because he destroyed her hometown and killed her father. Her initial motivation for joining up with Cloud on his journey is try and stay as close to him as possible. She senses something isn’t right with him after she runs into him at the Midgar train station. She had not seen him in years, and Cloud seems to have hazy memories of when their last encounter was. Later in the game when Cloud has a mental breakdown, it is his relationship with Tifa that pulls him back to reality. Tifa helps Cloud realize that he is not a creation of Shinra, and that he is, in fact, the real Cloud. She helps him remember who Zack was, and it truly cements Cloud’s motivation for continuing on his journey after Sephiroth.
