Since it has come to this, it is regrettable but...

...by these hands of mine, Suzumiya-san will... (The end of the sentence was intentionally truncated by the artist, making translating it into English slightly compromising as English grammar doesn't end with the verb like Japanese. Based on Kyonko's reaction and the abilities of Koizumi's esper power, it can be assumed that in proper English, the phrase could be transcribed as "With these hands of mine, I will take care of Suzumiya-san" or a similar equivalent.)
