Narrative:

We were training for night takeoff and landing practice at dab runway 17R (right traffic). After we took off, we checked right and turned to downwind. We saw strobe light to inside our cockpit. That time, small aircraft Y was just above us, so we tried nose down to avoid. But it was 10-20 ft above us. This small aircraft Y didn't know he was flying above us. I told tower, tower also didn't know. And tower told small aircraft Y to extend downwind, then tower gave us a 'cleared to land.' so we started turn to base, and also small aircraft aircraft Y turned to base. So again, we had another near midair collision. Finally tower instructed other aircraft to make left 360 degree turn to follow me.
