Combo:
- Numerical notation: AB ~ [AB] (17 hits) ~ D ~ 66 (dash cancel), 5C (2 hits), 2C (3 hits), 2AB (2 hits), 236A ~ A, OMB, 236236A, 236236A, 236236A.
*The 2 last supers can be done more easily by holding A until you see the 'SP' text on the screen.
- Arrows notations: AB ~ Hold AB (17 hits) ~ D, →→, C (2 hits), ↓ + C (2 hits), ↓ + AB (2 hits), ↓↘→ + A ~ A, OMB, ↓↘→↓↘→ + A, Hold A (until see 'SP' on the screen), Hold A (until see 'SP' on the screen).
- Generic solution: AB ~ [AB] (17 hits) ~ D ~ 66, any 10-hit combo, 236236A x 3

Detailed Explanation:
AB (start the combo with 'All Out Attack'),
when Sho reaches Yu press AB again and hold it (you must get 17 hits. If you don't get all the hits, you don't get the fatal counter. And the fatal counter is necessary to link 3 supers in the end),
press D,
press 66 (cancel the 'All Out Attack' follow-up with the dash cancel),
5C (2 hits. You must to take care to keep Yu as high as possible or the combo will fail later),
2C (3 hits. You must to take care to cancel immediately after last hit of 5C to avoid to let Yu fall too much),
2AB (2 hits. You must take care to cancel immediately after the last hit of 2C. If 5C, 2C were canceled in the right timing this move will hit),
236A ~ A (cancel the previous move into 236A and press A again only once),
OMB (One More Bust. Press ACD when 236A~A touches Yu),
236236A (let Yu fall a bit and then catch him with this super. While the super is hitting start to hold the A button),
hold A and then release A (Hold A during the first super and then release it when you see the text 'SP' appears on the screen. It will make the super come out in the first frame possible. You can alternately just do 236236A again in the right time to make it link),
hold A and then release A (same from the last super. You can alternately just do 236236A again in the right time to make it link).
