A conclusion to fighting securing one success for former Emperor (7)
I believe the answer is:
akihito
'former emperor' is the definition.
The definition suggests a singular noun which matches the answer.
'a conclusion to fighting securing one success' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
'conclusion' could be 'hit' (hit is a kind of conclusion) and 'hit' is located in the answer.
'one' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Another definition for akihito that I've seen is " Japan's current emperor".)
