This is the code about half damage

if (◆戦闘タイプ == 0)     {

if (gs[ii][iic2].番号 == 1035 && gs[ii][iic2].個人 == 1)         {

if (▲ＤＭ > gs[ii][iic2].Ｓ体力最大 / 2)             {

▲ＤＭ = gs[ii][iic2].Ｓ体力最大 / 2;             }         }

Basically, if army battles, if Motonari and in battle with HP bar, if Damage against him is larger than his Max HP / 2, then Max HP / 2 (rounded down)

Note that this means it only happens when he's being attacked, not the attacker. He theoretically could take more than 1/2 HP in counterattack damage...
