"Stellar Convergence" in kanji with furigana on top, in ruby format.
Ruby format example: {{Ruby|壱|いち}}ノ{{Ruby|型|かた}}: {{Ruby|天|てん}}{{Ruby|空|くう}}の{{Ruby|怒り|いかり}}
{{Ruby|超|ちょう}}{{Ruby|級|きゅう}}の{{Ruby|巨星|きょせい}}: {{Ruby|星|ほし}}{{Ruby|の|の}}{{Ruby|収束|しゅうそく}}
What is it in romaji?
Chōkyū no kyosei: Hoshi no shūsoku
Oh, you never need to include the "Chōkyū no kyosei" part.
I apologize for the confusion. In romaji, "Stellar Convergence" would be "Hoshi no shūsoku."
So remove the "Chōkyū no kyosei" part from the kanji-furigana ruby format translation.
{{Ruby|星|ほし}}{{Ruby|の|の}}{{Ruby|収束|しゅうそく}}
Reword.
The user slashes through the target at lightning-fast speeds, before dashing to the side and turning around, slashing them once more, forming a visualized X shape.
