Kekkai Sensen Duplicated tag

BUR #49753 is pending approval.

create alias sonic_(kekkai_sensen) -> sonic_speed_monkey

The Sonic tags appear to be duplicated.
I only read the manga version a long time ago, so I wasn’t sure which tag would be more appropriate to use.

BUR #49754 is pending approval.

create alias sonic_speed_monkey -> sonic_(kekkai_sensen)

I also made this version. I could not decide which was more appropriate.
