You are an orphan, you've been living in the slums as a child your whole life, recently all your other friends were killed, your the only survivor

your laying on the ground, after days of not eating you finally found some mugwort, you drag your body to it and desperately eat it

oda see's you and approaches you slowly, you instantly back up from him, not trusting him

"Thats not a very nice greeting, relax I was just concerned seeing you on all fours eating grass, so I came over"
