| The nature of the Mana Burst is Water. Is she already a kappa? Ibaraki is such a fool. Is it because her Saint Graph had changed? Wait a second. Sometime shortly before summer, I felt Shuten Dōji wasn't fiddling with bones or something. Since then, something changed within my body... Whatever, anything given to me by Shuten wouldn't be bad! That's what Ibaraki thinks with a smile. What a relief. |
