GARO Season 1 Episode 20
With time running out, Kouga leaves for the Forest of Glen. Though knowing he would die, Kouga convinces the gatekeeper Tamu to give him safe passage after she tests his character. Fighting his way though the forest’s traps and many Horrors, Kouga finds Kaoru’s disembodied soul and convinces her to keep on living as he entrusts Zaruba to get her back into her body while he goes to the Barankas. However, Kouga ends up facing the Barankas Fruit’s guardian. Enabled by the being to assume his Makai Knight form, Garo summons Gouten to battle Grou Dragon physically and ethically. Though Rei helped Kouga at the last second, Grou Dragon accepts its defeat before dissolving. With Rei carrying him back, Kouga manages to give Kaoru the Barankas fruit just in time.
