Poor sad Tsuna D:
Ah, no, don't apologize, Tenth! [He rests a hand on one of Tsuna's shoulders, intending the action to be reassuring] There was nothing we could do, since none of us were here when it happened..
[He clenches a fist, tightly, determination in his eyes] Don't worry! I won't let anything like it happen again! As your righthand man, it's my duty to ensure the safety of the Family!
