(Details)

Style: Shield and Guts

(Story)
Alm the wolf, who is originally a data life form, get the new style-change.
The style is the hybrid of Wood Shield and Wood Guts.
This phenomenon is irregular and has bad effects for Alm, so he borrows a figure from another world to stabilise its power. The figure needs to have similar elements to the Style of Wood Shield and Guts, so the figure of Chesnaught are adopted.
